Alternative Origin Account
According to the account from Xingxi and Xing kao quoted by Hanyu da zidian, Qiu Yan, the fourth son of Lu Zhong, was enfeoffed at 侩; after the state was later destroyed by Zheng, his descendants adopted 侩 as their surname. The source explicitly says this differs slightly from the Lushi account.
