This respected scuba diving school offers PADI courses in English and Chinese, taught in an indoor pool and aquarium. Depending on your needs, courses are typically three weeks long. SinoScuba also periodically organizes diving trips in China and overseas. RMB2,800 includes everything except the four water open dives required for certification at the end of the course.
I dove with SinoScuba this weekend as part of their Shark Week(end) program. I got to pet sharks, play with a giant turtle and learn a bit about diving... and it was amazing. Highly recommended.
