Situ Jianguo, or known as Stu, host of "Stu's China Story", shared his 12-year experience in China as an invited guest. After travelling all the way from Britain to China 12 years ago, to learn Chinese language and culture, he now has been a famous vlogger in China, and hosts three shows.

In his shows, he uses British humor to share his stories, experiences and views about China in both English and Chinese.

"Humor has strength," he said, adding that he is looking forward to spend the next 10 years here in China and to take part in the 2022 Beijing Winter Olympics.
