I. Origin of surname:
The first origin: from the surname Jiang, from the descendants of Emperor Yan in ancient times, belonging to the surname with the ancestor as the title. After the reign of Emperor Yan of the Ting family for eight generations, some descendants migrated to the north of China and gradually merged with the local aborigines. They took "Dading" as their surname, and then simplified the compound surname of "Dading" into a single surname of "Da", forming a big surname.
The second origin: from the surname Feng, from the Fuxi family of Taihao, which belongs to the compound surname and is simplified to the surname.
There are many compound surnames in the descendants of the Fuxi family of Taihao, such as Dazhou, Dazhou, Dazhou, Dating, Daye, Mainland, Daxin, Dashu, Dadun, Dachao, Daidai, Dalian, Fei Da, Dali and Dalian.
The third origin: it originated from the Jurchen nationality and belonged to the ancestors' surnames after the surnames of Sumomohong nationality in ancient Bohai State.
In the Jurchen language of ancient Bohai ruins, "Da" means spring water, pronounced as dā, which is used to address elders in Jurchen language, and later pronounced as dū in Manchu Soren language. The ancient Bohai Kingdom was destroyed by the Liao State of the Qidan nationality, and its royal nobles took the surname of the former king as their inheritance.
In addition, the Manchu surname in the Qing Dynasty included Hersairihala, and later generations changed the single surname of Chinese characters to the big surname. Today, there is a village called Dajiawa in Shouguang County, Shandong Province. The members of the big clan in the village are either descendants of Emperor Yan or Manchu. There are several Koreans whose surnames are pronounced in Korean with Chinese characters, which is different from mine.
Ancestors of surnames: Yan Di and Dazuo Rong.
