Extremely popular journalist Chen Lingyan

In winter, if you want to experience the joy of outdoor skiing, you don’t have to go to a distant place, but you can do it in Wuhan.

On January 20th, the Four Seasons Ski Resort in Runqu Valley Scenic Area in Junshan New City of Wuhan Economic Development Zone held a media open day. Dozens of provincial and municipal media representatives took to the snow trail to experience the speed and passion on the snow with the citizens.

Relying on Zhushan Lake, this ski resort is the first outdoor ski resort in Wuhan, only 30 minutes’ drive from Hankou. At the same time, it is also a happy world integrating skiing, snow skiing, water sports, camping and parent-child paradise.

According to reports, the length of the snow trail of the Four Seasons Ski Resort in Zhongrun Qugu Scenic Area is more than 200 meters, and the slope is about 15 degrees, reaching the scale of the intermediate sports track. The real snow on the snow trails is made on site by professional snow makers-the snow makers constantly spray white snowflakes from the pipes, and after the snow accumulates to a certain volume, it is compacted and smoothed by professional snow rollers to form a series of snow trails.

This year, the ski resort has expanded to nearly 1,000 square meters, and the magic carpet has increased by hundreds of meters, reaching the highest point of the snowy road. There is a tourist reception center of nearly 1,000 square meters in the ski resort, and the ski hall is equipped with thousands of brand-new ski equipment, attracting skiers from Wuhan.

"I didn’t expect to achieve skiing freedom at home!" Mr. Zhu, a citizen of Wuhan, said with excitement after taking his children to experience it. Unlike the indoor ski resort, he jumped from the 200-meter-long snowy road and glided down, which felt like flying in the air. "It’s as refreshing as flying in the air!"

In addition to ski resorts, Zhongrun Qugu Scenic Area, which covers a total area of more than 600 mu, also has outdoor parent-child amusement parks, little red elephant parent-child amusement parks built in the Woods, unpowered facilities, slides, jungle adventures and other amusement facilities; It is also a paradise for camping enthusiasts, traveling through the forest path with three or two friends or family members and feeling the sunshine and breeze outdoors.

It is not so simple to learn all kinds of badminton skills.

1. Forehand ball rubbing:Stand sideways in front of the right net and hold the racket forehand. The racket is tilted to the right, front and upper with the forearm extended. When the racket is lifted to the highest point, the forearm rotates outward, the wrist flashes from backward to slightly inward, the index finger and thumb holding the clap grip the racket, and the middle finger, ring finger and little finger lightly hold the racket handle, so that the racket rubs the right bottom of the ball under the swing force of the wrist and fingers, and the ball rotates and rolls over the net.

It is not so simple to learn all kinds of badminton skills.

2, backhand rub ball:Before hitting the ball, the forearm is slightly raised, the wrist is bent forward, the back of the hand is about the same height as the net, and the racket face is lower than the top of the net, and the backhand face is used to meet the ball. When rubbing the ball, the right back bottom of the ball is rubbed mainly by the combined force of the forearm’s forward extension and outward rotation and the wrist’s adduction and abduction, so that the ball rotates sideways and rolls over the net.

It is not so simple to learn all kinds of badminton skills.

Pulling the ball is to sweep the incoming ball on the left and right sides of the body, below the shoulder and above the waist. haveThere are two kinds of forehand and backhand strokes.

1. Forehand stroke:Standing in the middle of the right field, the feet are parallel and slightly wider than the shoulders, the center of gravity is between the feet, the knees are slightly bent, and the forehand is held in front of the right shoulder. Before hitting the ball, the elbow is swung forward, the forearm is slightly rotated back, the wrist is slightly abduction to the back, and the racquet is brought back. When hitting the ball, the forearm rotates inward, the wrist is straight and flashing, the fingers grasp the handle, and the racket sweeps the cover at high speed from right back to right front to hit the ball. After hitting the ball, swing your arm to the left, take a step forward to the left with your left foot, and return to the center with your right heel.

2, backhand draw:The right foot crosses in front of the left side, the center of gravity is on the left foot, and the backhand grip of the right hand is in front of the left side. Before hitting the ball, the elbow is slightly raised, the forearm is pronated, the wrist is abduction, and the racquet is taken to the left.

Killing the ball is to obliquely press the ball hit by the opponent at the highest hitting point as possible. This kind of ball has great strength, straight arc and fast landing, which poses a great threat to the opponent. It is the main technique of attack. Killing the ball is divided into forehand killing straight line and diagonal ball. Overhead kill straight and diagonal balls, forehand flying assault kill straight balls and backhand kill straight balls.

It is not so simple to learn all kinds of badminton skills.

1, forehand straight ball (sideways take-off):The preparation posture and action essentials are basically the same as forehand golf. After the steps are in place, bend your knees and lower your center of gravity, ready to take off. When taking off sideways, lift your shoulders to the upper right to drive your upper arm, forearm and racket to lift up, so as to stretch your body upwards. After the take-off, the body leans back and shoulders back into an anti-bow. Then the right upper arm swings up to the right, the forearm swings back naturally, the wrist stretches back, and the forearm drives the racket to swing from top to bottom, so the grip should be loose. Then, the right upper arm is swung up to the right with the elbow leading, and the forearm is swung forward at full speed, which drives the racket to swing forward at high speed. When the hitting point is in front of the shoulder, the forearm is pronated, the wrist is slightly retracted, and the wrist is flashed to kill the ball. At this time, the fingers should suddenly grasp the handle and concentrate the explosive force of the wrist on the hitting point. The angle between the racket and the horizontal plane in the hitting direction is less than 90 degrees, and the racket hits the back of the bracket in the front, so that the ball goes straight down. After killing the ball, the forearm moves forward with inertia. Recover the racket to the chest during the return process.

It is not so simple to learn all kinds of badminton skills.

2, forehand diagonal ball (sideways take-off):The preparation posture and action essentials are the same as forehand straight ball. The difference is that after taking off, the body turns to the left and pushes hard to help the arm hit the ball diagonally. Overhead killing straight and diagonal balls: the action essentials and preparation posture are the same as overhead hitting high balls. The difference is that when you swing and hit the ball, you should concentrate on pressing down in a straight line or diagonal direction, and the angle between the racket face and the horizontal plane in the hitting direction is less than 90.

It is not so simple to learn all kinds of badminton skills.

3, backhand kill straight ball:The preparation posture and action essentials are the same as those of the backhand golf. The difference is that the swing force before hitting the ball is larger, and the angle between the racket and the horizontal plane in the killing direction at the moment of hitting the ball is less than 90 degrees.
