Is there a special school in Yantai Weihai, Qingdao? What you can learn can last for three years.

Hehe, it doesn't cost money to learn to capture and fight. You can buy a boxing sandbag and practice it yourself! In my previous experience as a special soldier, I got up at five o'clock in the morning to run 5 kilometers, found a training ground to play in the morning, carried cross-country for 5 kilometers before lunch, and played basketball or football in the afternoon. 5 kilometers before meals in the evening. Before going to bed at night, 100 sit-ups, 300 push-ups and 200 squats with legs together. Set yourself a 10 km hiking and 60 km cycling every week. Stick to it for three months, and you will find that you are strong and have great strength. Fighting is not a problem, and you can easily deal with four or five adults.

By the way, we used to do 500 sit-ups, 800 push-ups, 200 squats, weighing 65 kg, and having an abdomen in half an hour.
