The teacher pointed to Xiaohua's Renzhong point with one hand and held his Hegu point (the triangle between thumb and forefinger is about 2 cm) with the other hand, and asked the students to fan Xiaohua with fans and straw hats. No? After a while, Xiaohua recovered. The teacher gave Xiaohua a bottle of ten drops of water and a bottle of mineral water.
