In hot weather, Chinese people enjoy eating refreshing cool bowls of 綠豆湯 lǜdòu tāng / liuhdow tang [literally] “green bean soup”, which is actually mung beans served in sweetened water (刨冰 bàobīng / bawbing “shaved ice” or 煉乳 liànrǔ / liannruu “condensed milk” are sometimes added).

Mung beans are also eaten in the form of sprouts and noodles. Here is a cool time-lapse video shot over three and a half days (2'50") showing mung beans germinating ("[Time-Lapse] Mung Bean Germination"):

炎熱的夏天，大家都喜歡來碗綠豆湯消暑！因為許多人都沒有注意到『綠豆』的原產地是印度，所以英文名字根據梵文 मुद्ग / mŪgd , "mung bean" 才是正確的叫法。Green bean 指的是四季豆。
