After the 20 15 concert, Yifeng Li fans reached a Green Sea agreement with Yifeng Li. Yifeng Li himself didn't know it, but the fans promised to hold the concert in Yifeng Li seven years later.

From 2007 to 20 15, the concert was just seven years, and the concert was a green ocean. Yifeng Li read this letter to his fans, which wrote: Seven-year itch, if you itch, I will scratch. 15+7=22 years, which is the Green Sea Covenant in 2022.

When interviewed by a reporter, Kuy stopped tracking and asked Yifeng Li if he knew about the Green Sea Convention. Yifeng Li said he did, but in a recent interview, Yifeng Li said he was preparing.
