Tanwan Company applied to register Zha Zhahui’s trademark in April 2018, but was rejected by the court because of suspicion of insulting personality. Later, Tanwan Company applied for the Zhazhahui trademark again, but was still rejected.

The origin of the title Zha Zhahui is actually because Zhang Jiahui is from Hong Kong and his Chinese is not very good, so every time he introduces himself, he pronounces his name as Zha Zhahui. Later, netizens spoofed this homophonic meme and regarded it as Zhang Jiahui's nickname, but Zhang Jiahui didn't like this nickname very much. He once said that he felt that the whole China was laughing at me. But netizens still insist on calling Zhang Jiahui "Zha Zhahui".

In June 2017, Zhang Jiahui cooperated with Tanwan Company as the spokesperson of Tanwan Company, but after the contract between the two parties ended in 2018, they did not cooperate again. In April 2018, Tanwan Company applied to register Zha Zhahui's trademark, but it was rejected by the Beijing court. Then, its application again this year was still rejected by the court. Because the word "Zhazha" means damaging the personality of others and is a derogatory term, which violates the registration regulations above, the application of Tanwan Company was not approved.

Netizens enjoy this nickname endlessly, but Nick Cheung himself has made it very clear that he does not like this title, and it feels like the whole of China is laughing at him. Some netizens often publicize other people's personal insults as jokes, but they don't know how despicable and shameless this behavior is. The behavior of Tanwan Company encourages this shameless trend and has a very bad impact on society.

Tanwan Company should reflect on its own behavior instead of insisting on registering this insulting trademark. It is really shameful to ride on this kind of popularity. The court's decision is very correct. Netizens should also carefully review their behavior to see if it is what they should do as fans. Respecting others is our most basic human etiquette.
