It is a song sung by Shanmao and Danjuan (Lin Xieyang & Zi Tangsu). The lyricist is Hu Buju. The original song is Xia Lian, a piece of pure music written for Otokaze. This is an ancient style of music. :

The academic community has not yet given an authoritative definition of what ancient style music is. But the general characteristics can be summarized as follows: the lyrics are classical and elegant, like poetry and songs, the tunes are beautiful, focus on melody, and use many ethnic instruments, without the metallic feeling of rock music and the heavy feeling of classical music. But according to the mainstream classification in 2013, ancient music can probably be classified as new age music or pop music.

Listening to ancient music is like tasting tea. When tasting tea, you can talk about the name of the tea, smell the aroma, observe the shape and taste of the tea. When listening to ancient music, you can also approach it from all angles - the melody, without the hustle and bustle, is like clear flowing water; the lyrics are carefully crafted, like a series of Tang poems and Song lyrics; the artistic conception is profound and far-reaching, making people think about it. The ancient wind rolls in the floating clouds.

Composing music, writing lyrics, and singing are not for fame and fortune, but for the love and emotion in my heart. Such spiritual sounds with pure motives are naturally beautiful. However, because there is no systematic promotion, these shining pearls have been scattered in the vast sea of ????the Internet.

The early ancient-style songs were mainly written and sung to the soundtracks of domestic Xianxia Chinese-style RPG games, such as the "Legend of Sword and Fairy" series, "Xuanyuan Sword" series, "Peerless Two Prides" series, etc. By 2013, due to the rise of ancient-style music on the Internet, many original music teams that mainly create ancient-style music have been established, and more and more original works are being produced.
