As soon as you start looking for a martial artist, go to the Lucky Charm Qr. straight away, and ask any person if they know a martial artist (you must ask people in the Lucky Charm Qr. though), and they point you to Zhangyu. Go see Zhangyu, and learn DAN from him. After this, go to Lotus Park and learn GON from Jianmin. Now go to the Guang Martial Arts School and go through the normal procedure to learn JIE. Afterwards, Ryo will automatically ask if Zhoushan knows of any other martial artists. As you've already seen Zhangyu and Jianmin, he tells you to ask at the Sunny Capital Pharmacy in the South Carmain Qr. Go there and talk to the owner, and he'll eventually tell you about Guixiang, and you discover that her late husband was a kung fu master. From there you find Guixiang and the game continues as normal.
cool.
