Is Ole in Wu Shang a socket?

That's not true. Wu Shang Ole's full name is Wuhan Wu Shang Outlets Commercial Management Co., Ltd., formerly known as Wu Shang Zhongyuan Plaza, which is a wholly-owned subsidiary of Wu Shang Group. Outlets, namely "brand direct selling shopping center", is a commercial form, which originated in the United States and flourished in Europe. They come from different sources.
