Who poisoned Wang Jie’s voice when he was at his peak?

Wang Jie was very popular in Taiwan at that time and made a lot of money. After immigrating to Canada, there were more than a dozen luxury cars parked in front of the mansion. However, due to his addiction to gambling, he lost hundreds of millions, so he returned to his hometown in Hong Kong to develop again and signed a contract with Yeung Shoucheng's Emperor. It's a pity that the Emperor is not as good as the Taiwanese music scene. He has Nicholas Tse who he wants to admire. Nicholas Tse, who sold himself to the Emperor because of the huge debt owed by his father Xie Xian and had a ten-year contract, must be popular in order to make money for him, and he is arrogant and has high self-esteem (of course he also has this Wang Jie (capital and qualifications) has become a serious obstacle. King, who dominates the Hong Kong music scene, has always been ruthless to his opponents and disobedient ones. This is where the rumor that Wang Jie was poisoned by his company came to light, and the Emperor promptly sent a message saying that he was an alcoholic and so on.
