Sometime in the middle of 2006, Front Line discussed about how Yang Chengang came into trouble with the copyright holders of a song he wrote that became an instant hit throughout Asia. Yang Chengang was a school teacher in China and the artist of the popular song "Mice Love Rice". In the mid 1990s, he sold the copyright of the song to Emperor Entertainment Group and then later signed another agreement with another record label. When the second record label distributed his song, the original copyright holder Emperor Entertainment Group sued the other record label only to find out that Yang Chengang was the one who double sold the song.
