Four great sons of the Republic of China

The four sons of the Republic of China (or modern four sons) refer to the children of the four noble families in the Republic of China. There are different opinions about the identity of these four people, but both Zhang Xueliang and Yuan have different opinions. The fourth son is as follows (introducing his father, mainly in the official position of the Republic of China): Zhang Xueliang, Northeast Grand Marshal Zhang Zhangzi. Yuan Hanyun, whose real name is Ke Wen, is the second son of Yuan Shikai, the first president of the Republic of China. Pu Dong, the royal family of Qing Dynasty, was the son of Belle Zai and the king of Jia County. Son of Kuomintang Prime Minister Sun Yat-sen, son of Zhang, governor of Zhili. Zhang Xiaoruo, the son of Zhang Jian, the chief agricultural and commercial officer. Lu, son of the Governor of Zhejiang Province. Duan Hongye, the son of Duan who was in power during the Republic of China. According to the Supplementary Notes on Continuing Hongxian Chronological Poems, the four sons of modern times are (Yuan), (Yu), Zhang Xueliang, Lu, and Xiao Ruo, the son of Zhang Jian. There is also a saying: one is Pu Dong, the owner of the Red Bean Pavilion, the other is Yu, and the fourth is Zhang Xueliang. Zheng's Biography of Yuan lists Zhang Xueliang, Lu, Zhang Xiaoruo and Yuan, excluding them. Bai believes that due to the death of Yuan Shikai, the four sons do not include his son Yuan, which should be listed as.
