Where can I learn good visual display and window design clothes in Shenzhen?

I only know that there is a 998 exhibition in Shenzhen and Pan Am (Pan Am has a good reputation on the Internet). They have a website. If you look at Baidu, it seems that there is a sailor in Guangzhou (man doesn't know if it is the word), and people in the industry still know it. Zhonghe fashion in Beijing is famous and seems to be more formal.
