Some people think that the Shang characters in Oracle Bone Inscriptions are like swallows, meaning swallows. According to the ancestral legend of the Yin people, their ancestor Qi (xiè) was born by his mother Judie who swallowed the eggs of swallows. This legend is recorded in The Book of Songs, Ode to Shang and Xuanniao: "Xuanniao was born in the destiny, and Shang was born in the world." Shuowen also said that "swallows, dark birds are also", which shows that dark birds are swallows.
Because the Yin people thought they were descendants of Yan people, they took the merchant of Yanziyi as their family name. Some people say that it is far-fetched to interpret Shang characters in Oracle Bone Inscriptions as swallows, and there is no evidence to prove that Shang characters mean swallows in ancient literature. So this statement is hard to believe.
