Woke up - Hysung and Lingling (Jingjing and Lingling are brother and sister)
Drunk - Mei, Liqui, Huian, and Wang (drinking more water due to a shortage of beer)
Happy - Lanyuing, Qui, and Rong (had a party that night by stealing others' beer)
Sick - Shuang and Yan (suffering from food poisoning - ate too many rats and snakes)
