Why is Jia Lian called Master Lian?

Jia Lian is called Sir Zhong, because he has a brother named Jia Cong, so Jia Lian is called Sir Zhong. Jia Lian, also known as Master Lian, is a character in China's ancient novel A Dream of Red Mansions, also known as The Story of the Stone, which is one of the four classical novels in China. Relatively speaking, A Dream of Red Mansions is a human novel with world influence, recognized as the pinnacle of China's classical novels, an encyclopedia of China's feudal society and a master of traditional culture.

Some people may ask, since Jia Lian is the eldest grandson of the government, why not call him "Master Lian" but "Uncle Lian"? This is because the grandmother's eldest grandson is Jia Zhu, the eldest son of Fannie and Freddie. Jia Zhu was born earlier than Jia Lian, who was the eldest grandson of Rong Guo Fu, and Jia Lian was born later. According to the theory of family status of the Rong-Guo government, Jia Lian can only be Master Lian. ?

Jia Lian ranks second in the fourth generation of Guo Rong government, which does not affect his position as the eldest grandson of Guo Rongfu. The eldest grandson must be the eldest son of a big family. Although Zhu Jia is older than Jia Lian, he is only the second wife. Jia Lian is the eldest grandson of the government and has nothing to do with family ranking. ?

The ranking order of Rongguofu is Uncle Zhu (the eldest son of the second house), Lian Jialian (the eldest son of Rongguofu), Bao Baoyu (the second son of the second house), Huan Jiahuan (the third son of the second house) and Cong Jia Cong (the second son of the second house). The five of them are the fourth generation of the government, and they should be called in this order. ?
