The third is Cupping. What a weird name in English. Briefly speaking, we light a fire - (you can use a piece of paper, but in China, we will use some herb which I have forgotten...) - in a cup, then upsidedown flip the cup, and press it on one's back heavily. It is obvirously obviously so that the fire will go out when oxygen beside these cups is used up. The most interesting part is that the hot air in the cups will keep stimulating your back, and your back is absorbed into those cups which even makes you a little hurt (or: which will even hurt you a little). After all these cups cool down we bring them off your dotted back and then have a good sleep. 
All the three methods are useful for colds and some other diseases caused by cold weather.

This was a really good entry, but there were mistakes here and there. The reason for your mistakes is mainly because of the tense you use! If you start talking in past tense, stay in past tense, or if you talk in future, stay in future. There were a few times when you used the adjective instead of the noun, like dry instead of dryness or uncomfortable instead of discomfort. This entry was really long, and your efforts were really good! Keep practicing because your English is really good already! 

This is my first wrighting in writing/time writing/entry on italki and hope to carry on in the next few months.
