Suppressed
When signing the contract the terms were so that Yang Kun would only get the rights to the song "Indifferent". As for other songs, they didn't appear in the contract.
Zhang Xiaohua was worried that Yang Kun would behave like Wang Jingwen, so he applied a small trick in the contract.
He didn't expect him to bring a lawyer to negotiate with him.
However, in all honesty Yang Kun's request was reasonable.
A lot of entertainment firms in order retain their big stars and prevent them from leaving would sell their artists some of the copyrights. For example selling them the rights to perform the songs commercially while retaining the copyright for movies and Tv soundtracks.
But Zhang Xiaohua retained all the rights.
What worried Zhang Xiaohua was that if he agreed to Yang Kun's terms, he would lose his bondage and binding force over him. Currently if Yang Kun left all he would be able to take with him would be the song 'Indifferent'.
