双赢就是中国赢两次

Meaning

"Imperial Three Sons" (帝国三子) refers to the three members of Chinese boy band TFBoys: Wang Junkai, Yi Yangqianxi, and Wang Yuan. Around 2014, their fans' data manipulation ability was so strong that other fandoms mocked them as using bots, saying they "invaded data like imperial powers." Another theory: the agency boss was superstitious, so the three names include mountain (凯), water (源), and emperor (玉玺/imperial seal). Later, Wang Junkai said on WeChat "Four Leaf Clover, the empire is strongest," cementing the name.
