Yes, you read that correctly. In 1994, a Chinese film production company called Beijing Film Studio produced a martial art film with the world's greatest detective as its star. The film titled Sherlock Holmes and the Chinese Heroine or Sherlock Holmes In China, Holmes played by a less known actor named Alex Vanderpor (his IMDB profile only lists this film on filmography) and his partner Dr. Watson, portrayed by Chinese actor Zhongquan Xu (who only has 4 movies to his credit on IMDB) arrive in China to help in the war against opium traders. Apparently, the character is so popular in China, several non-Canon stories were published there along with this film.
The film is available to watch on Youtube, unfortunately it's in Chinese without subtitles.
