Which Nike discount store is the cheapest in Beijing?

The Nike factory in maliandao is ok, sometimes it is very cheap. I caught it once. On the basis of discount, buy more than two pieces and then get a 20% discount. Usually you can get at least 30% discount. Nike's factory stores should be fidelity.

In other places, the top grade discount seems to be quite high, including Wangfujing Gongmei and lishuiqiao, and lishuiqiao seems to be a little bigger. But some people say it's fake, and the details are not clear.
