Gan Ziyi takes the idiom "Gan Ziyi" because Gan Ziyi is aimed at urbanites. Although we stay up late to work overtime, play games and drink, whether for fighting or to accompany our friends, we are happy even if we want to, but staying up late to drink is really harmful to our health. After a long time, problems keep coming, which is our body's "protest".
Gan Ziyi can solve the sequelae of drinking and staying up late, and make you refreshed and full of energy the next day, not only psychologically but also physically.
