What painful memories, history is always strikingly similar, a few pictures see through history.

The ancients did not deceive me. This posture is really comfortable.

When I was a child after 1980, I was scolded by my parents for only watching TV;

When I was a child after 90, I was scolded by my parents and only knew how to play computer.

After 00, I am being scolded by my parents who only know how to play mobile phones;

I used to be addicted to smoking cigarettes, but now I am addicted to playing mobile phones.

I used to beg from passers-by on the roadside, but now I ask netizens for money in front of my mobile phone.

Watch less mobile phones and spend more time with your family. The scenery outside is actually beautiful.

In the past, friends’ parties were all about going to the smoking house, but now friends’ parties are all about taking a shower.

The couple used to smoke together, but now they watch it together.

History is always strikingly similar. In the past, wearing a yellow vest was a royal, but now wearing a yellow vest is a beautiful group.

I sent prisoners together in previous lives, and now I send people meals together.

I used to keep my knife, but now my bag is carried everywhere.

In the past, the Kingsguard was very arrogant when going out. Now, when it rains, you have to run. If you don’t run, you will have no money.

The only constant is that it used to serve people, and now it still serves people.

I used to stand on the side of the road with a stick and a bowl, but now I walk on the road with a mobile phone and a tube.

I guess your posture is like this now.

A few decades ago, a foreigner put forward a theory, "nipple music". It is to create a closed circle and trap the energy of ordinary people in it, so that they have no strength to think about themselves. And this circle is mobile phones and television.

Put down the phone and look up more.

"Collect" the most complete schedule of badminton matches in 2023.

Time has entered 2023, and badminton has entered a new year. With the normal development of sports events in 2022, domestic and international badminton events will flourish in 2023! After three years, badminton fans can feast their eyes again!

What are the badminton events that should not be missed in the new year? Let’s talk about domestic badminton events first. On January 1, 2023, China Badminton Association made careful arrangements for badminton competitions and activities in 2023, both professional and amateur. There are competitions and activities for the old, middle-aged, young and young people, and there is an upsurge of "national fitness" in China!

I. Arrangement of domestic badminton events and badminton activities

In 2023, the national events drawn up by China Badminton Association include: National Badminton Individual Championship, National Badminton Team Championship, National Badminton Individual Championship and National Badminton Team Championship; China Badminton Club League A and China Badminton Club League B; National Youth Badminton Championship, National U Series Badminton Finals, National Fitness Badminton Competition, etc. The time starts in February, and the specific arrangements are as follows:

Second, international badminton events

Looking at the World Badminton Federation tournament table, in 2023, there will be 4 events of Super 1000, 6 events of Super 750, 9 events of Super 500, 11 events of 300, and 10 other important events. It is stipulated by the World Badminton Federation that the top 10 players must participate in more than 750 events (unless injured). Therefore, badminton events in 2023 are intensive and quite exciting!

January

January 10th-15th, Malaysian Open, Super 1000.

January 17th-January 22nd, Indian Open, Super 750.

January 24th-29th, Indonesian Masters, Super 500.

January 31st-February 5th, Thai Princess Masters, Super 300.

At the beginning of the new season, Guoyu is fully fired and goes all out to fight in the international arena. Guoyu men’s singles Shi Yuqi, Lu Guangzu, Li Shizhen, Weng Hongyang; Han Yue and Zhang Yiman of women’s singles; He Jiting/Zhou Haodong, Tan Qiangren/Yu Xiang in men’s doubles, Li Wenmei/Liu Xuanxuan, Zhang Shuxian and Du Yue in women’s doubles; Wang Yilu and Huang Dongping of mixed doubles all signed up for the competition.

The high-level competition with four back-to-back stops is a great test for athletes. Zheng Siwei/Huang Yaqiong and Chen Qingchen/Jia Yifan only participated in the first two high-level races, while Chen Yufei, He Bingjiao, Wang Zhiyi, Liu Yuchen/Ou Xuanyi and Liang Weikeng/Wang Chang participated in the first three races.

The first two stops (Malaysia Open and India Open) of the Yellow Duck Team were combined, but they were dismantled in the third stop (Indonesia Competition) and the fourth stop (Princess Thailand Competition), namely Du Yue, Wang Yilu’s partner, Feng Yanzhe, Huang Dongping’s partner, Yu Xian, the women’s doubles team, Zheng Yu and Du Yue’s partner, Zhang Shuxian and Liu Sheng, one of the women’s doubles champions in the 2022 World Youth Championship.

There are also some new talents born after 00, such as Chen Boyang/Liu Yi in men’s doubles, Li Yijing/Luo Min Xu in women’s doubles, Jiang Zhenbang/Wei Yaxin in mixed doubles, and Cheng Xing/Chen Fanghui will also appear in Indonesian Masters and Thai Princess Masters. We expect Guoyu’s main force and rookie to bring wonderful games to the fans at the beginning of the new year!

February

Mainly intercontinental team events, mixed team events in Asia, Europe, Africa, America and Oceania, these are the qualifiers of this year’s Su Cup. As China is the defending champion and the host, China can directly enter the Su Cup lineup. Starting from the tacit understanding degree of training novices and cultivating new combinations, China team probably won’t send the main players to participate in the competition. In this way, the main force of Guoyu who participated in the January competition will have a period of time to adjust their state and prepare for the important competition in March.

March

March 7 -12, German Open, Super 300

March 14th-19th, All England Open, Super 1000.

March 14th-19th, China Ruichang Masters, Super 100.

March 21 -26, Swiss Open, Super 300

March 28th-April 2nd, Spanish Masters, Super 300.

This month, there are four consecutive European competitions, among which the Super 1000 All England Open is the most concerned event. In addition, the China Jiangxi Ruichang Masters, which is held at the same time as the All England Competition, is a new event, which will be a stage for young players, and young players of Guoyu will naturally not miss this excellent exercise opportunity.

april

There are not many high-level competitions in April. Except for the Super 300 Masters in Orleans, France, which was held from April 4 to 9, all other events were intercontinental individual championships. The more important event was the Asian Badminton Individual Championships held in Dubai from April 25 to 30, which is equivalent to the Super 1000 event, and the main force of the national badminton should participate. There are also the Pan-American Championship from April 27th to 30th, and the European Championship from April 25th to 30th.

May

From May 14th to 21st, Sudirman Cup was held in Suzhou, China.

May 23 -28, Malaysia Masters, Super 500

May 30th-June 4th, Thailand Open, Super 500

There is no doubt that Asia is the place with the highest level of badminton. It started from Asian competitions in January and returned to Asia again in May. May is the beginning of the 2024 Paris Olympic Games points competition. This month, the focus is on the Sudirman Cup mixed team competition, with Guoyu playing at home, with the goal of defending successfully. Of course, the strength of Japan, South Korea, Indonesia, Malaysia, Denmark and other teams should not be underestimated! In Suzhou, fans can watch the Su Cup once again, which is also the third time that domestic fans can watch the ball again. Now tickets for Su Cup have been sold.

June

June 6 -11, Singapore Open, Super 750

June 13th-18th, Indonesia Open, Super 1000.

June 20th-25th, China Taipei Open, Super 300.

The Indonesian Open has always been a highly regarded event, and it has the title of "Devil’s Home". Even Lin Dan failed to win the Indonesian Open. Since he first fought in the Indonesian Open in 2002, Lin Dan has participated in the Indonesian Open eight times in 2002, 03, 04, 09, 11, 15, 16 and 17, but his best result is only the semi-finals, and he has not reached the final once.

July

July 4 -9, Canadian Open, Super 500

July 11th-16th, US Open, Super 300.

August

August 1 -6, Australian Open, Super 500

August 8 -13, New Zealand Open, Super 300

August 21 -27, World Championships

The World Championships is also an annual badminton feast, and it is also the most concerned event for every player. How many players have become famous here in World War I, such as Marin of Spain, Indanon of Thailand, and Xie Dingfeng/Su Wei of Malaysia, all of which have sprung up in the World Championships. For every player, the World Championships are an indispensable puzzle for his career.

September

September 5 -10, China Open, Super 1000,

September 12th-17th, China Hong Kong Open, Super 500.

There has been no competition in China for nearly three years. For domestic fans, it is undoubtedly the gospel of many fans to reopen the competition in 2023. The atmosphere of watching the ball on the spot is completely different, and I look forward to the re-launch of domestic competitions this year.

October

October 10th-15th, Finland Open, Super 500.

October 17th-22nd, Danish Open, Super 750.

October 24 -29, French Open, Super 750

October 31st-November 5th, German Hailu Open, Super 300.

In October, the competition returned to Europe, and the Danish Open and the French Open were at a higher level. At the same time, the Danish Open is also one of the events that everyone pays more attention to. However, for fans, it takes jet lag to watch the live broadcast of European events, and the events are very dense, but the excitement of these stops is really good.

November

November 7 -12, Korea Masters, Super 300

November 14th-19th, Japanese Masters, Super 500.

November 21st-26th, China Masters, Super 750.

November 28th-December 3rd, India’s Saimodi International Competition, Super 300.

There are also four races in November, but it is close to the end of the year. At the same time, back-to-back races are held, and the fatigue of many players is rising. It is easy for players to retire in these races.

The competition in December mainly focuses on the year-end finals, which will be held on December 13-18 at a location to be determined. The year-end finals, which is the last event of the year, will compete for the championship of the year-end finals with the top eight singles players or eight groups of doubles players, and each game will be splendid and not to be missed.

After VAR awarded OPE a penalty for Liverpool handball, Salah shot wide and missed the penalty.

Mohamed Salah missed a penalty for OPE against Bournemouth at noon on Saturday.

VAR awarded Liverpool handball

Salah broke the reds’ first goal of the season.

Klopp lost to relegation fighter Bournemouth.

What happened? Liverpool were awarded a penalty for Adam Smith’s handball, which gave them a chance to equalize the score against Bournemouth. Salah stood up for Liverpool’s first penalty of the season and uncharacteristically missed the ball!

The bigger picture: Liverpool hope to take advantage of last week’s 7-0 victory over Manchester United on the South Coast. Philip Bill scored the only goal of the game, and the Red Army fell behind. They thought they had a chance to return to the game before Salah missed the penalty.

Quantum machine learning: the intersection of quantum computing and artificial intelligence

With the continuous progress of technology, the concept of quantum computing is more and more widely known. As a new computing paradigm, quantum computing is very different from traditional computing methods. It can deal with problems that traditional computers can’t handle, which makes quantum computing have broad application prospects in the field of artificial intelligence. Quantum machine learning, as an important field where quantum computing and artificial intelligence intersect, has a wide and far-reaching application prospect. This paper will introduce the basic concept, principle and application of quantum machine learning, and analyze its future development trend.
