Another way is Taoist gastric lavage. Many people do this when crossing the valley: 1. Boil the water of the previous day, add the water just boiled this morning, and mix 2.5 kg each. This is called yin and yang water. Drink it in one breath. 2, it will make you excrete completely or vomit, but don't worry, it will definitely make you refreshed. Be sure to drink this yin and yang water from 5 to 7 in the morning. 4, insist on 3 days, eat as little as possible every day, do not eat staple food, it is best not to eat. 5 or 3 days will make you suffer 10 Jin, but it is very comfortable and people will be very relaxed. Taoism is a good way to keep in good health. I hope I can help you.
