They are people of the same era, and the only connection is that they are all calligraphers. Later, Cai Nang replaced Cai Jing as Song Sijia. One is Cai Xiang, a bachelor of Duanming Temple, who is a famous minister of Li Qing (known as the "famous minister of Song Dynasty" in history), and the other is Cai Jing, who is a scholar with five talents and a great teacher. They are ministers of the same town, surname, clan and dynasty, and the two brothers are cousins.
Introduction of the two.
Cai Xiang (10 12-1067) was born in Xianyou, Xinghua, Northern Song Dynasty (now Xianyou County, Fujian Province, China). China was a politician, calligrapher and tea expert in the Northern Song Dynasty. He is the author of "Tea Story" and "Litchi Book".
Cai Jing (1047-1 126), long word. Xinghua Xianyou (now Fujian) in the Northern Song Dynasty. He was the most greedy and powerful person in the Northern Song Dynasty, and also a calligrapher.
Since the Ming and Qing Dynasties, some people thought that "Cai" should be Cai Jing. Later generations looked down on him, so they changed Cai Jing to Cai Xiang and thought that Cai Jing's artistic achievements were better than Cai Xiang's. In addition, from the age of life, Cai Xiang is ahead of Su, Huang and Mi Zhu, but Cai Xiang is last, which is contrary to common sense.
