The title of Azuki-chan in Hong Kong is "Classmates" in Chinese.
Whoa! Who is "Kun-chan"? His real name is Ken...mmm! not Ken but Daizu!!
This article says that Azuki-chan and SAIMON Fumi's "Dokyusei (classmates)" has the same title in Hong Kong.
Here's my translation of introduction of characters, with a poor grasp of the Chinese language. :)
Jidama - An active girl of the class.
Makoto-kun - A "poker-faced" boy admitting that he doesn't like girls.
Kaoru-chan - A mild, good and the most beautiful girl of the class.
Azuki-chan - Heroine, 5th grader of Elementary School
Yunosuke-kun - A transferred student. A mild-mannered boy.
Yoko - A rich girl acting high-handedly.
Kun(?)-chan - Cocky and competitive.
Tomo-chan - Leader of the class, a "big sister" of everybody.
