Why do I always hear fishing boats singing at night, which is totally different from CCTV weather forecast? Are there two fishing boats singing at night?

The fishing boat sings late is adapted by Lou Shuhua according to the ancient song Return, and by Jin Zhuonan according to the traditional "double board" in Zheng Song. It is widely said that the first half of Louben is the same as that of Jinben, and the second half is Louben's unique music. (Excerpted from Baidu Encyclopedia)

So what you are likely to hear is the first and second parts of a piece of music by Lou Ben.
