毕竟他姓吴
[bì jìng tā xìng wú]
Translating into 'After all, he surnames Wu,' this netname seems rather simple on its surface since the meaning is fairly direct: it refers to the person’s surname being Wu. In China, some people use characteristics or elements about themselves (e.g., birth date, occupation or hometown) as part of online IDs, possibly to keep it personal, humorous, memorable or as an inside joke.
