Xu Kai (許凱) gains fame after shooting a Chinese drama, Story of Yanxi Palace (延禧攻略) and the hot trend remains despite airing its finale. A few days ago during an autograph session in China, it attracted big crowd of fans to support him but he was criticised for his Mandarin in terms of writing. Apparently one of his fans was named “hot spicy soup” (麻辣燙), but Xu Kai wrote it in a different Chinese character for the last word (麻辣湯) and his fan also pointed he failed to write it even after a minute. As he was surrounded by many gossips lately, Xu Kai decided to upload photo of himself writing (麻辣燙) on Weibo as punishment on 9th October 2018.
