Yongzheng's cleverest son is the fifth brother Hiroyuki, who expressed his idea of staying away from the battle between the imperial court and the throne by pretending to be stupid and ignorant. Hongzhou was the younger brother of Emperor Qianlong after Yongzheng, but Qianlong was very tolerant of this younger brother. Even though Hongzhou did a lot of ridiculous things, Qianlong didn't take it to heart and still took care of this younger brother. This is mainly because some things that Tian Hong usually does are fake, which is a way to protect himself. Actually, he knows everything.
Hongzhou usually does a lot of ridiculous things. For example, he will openly beat the extraordinary minister in the court, and even contradict King Qianlong, but Qianlong doesn't care very much and is very angry, which also achieves the purpose that Hongzhou wants, because Hongzhou only does this to let Qianlong know that he has no idea about the throne and that he has no ability to be king, which just reflects Hongzhou's smart side. Gan Long loves poetry very much, and his younger brother Hong Zhou has a high level in both poetry and prose. Hong Zhou's poem "Jin Zun Yin" killed the king of Gan Long, which left a great impression and high status on later generations.
The poem "Golden Zun Yin" is very beautiful, which appropriately expresses Hongzhou's desire to stay away from court disputes, and the clever Gan Long also knows his brother's inner thoughts from this poem, which is also the main reason why Gan Long was very tolerant of this brother later, and Gan Long cherished the brotherhood between him and his brother more in the struggle for the throne.
