谜底 -- 给需要的旁观这场喜剧的朋友们。

"Source of Love", translated from the famous Chinese (云南) folk song "小河淌水", sung by Sofia Kallgren, a very hot pop singer from Sweden.

The Chinese version is the work of 吴静.

The links are pirated from other forums of Wenxuecity and Creader.

A kind reminder: 楚江 has more than one younger sister, and Sofia Kallgren and 吴静 could be her sisters. 小千has kindly called for everyone's caution earlier. And 北京二号 has never claimed in any form that these are her work.

Did you laugh?

Have a good day!
