Gu Niannian searches thousands of miles for her father relying on a single note. Her father Gu Yanqiu is a decadent and lazy man, but completely awakens due to his daughter's arrival.

What is persistently yearned for is sure to have an echo; crawling out from the mud, they will ultimately dominate the mountain ravines.
