hii..can u tell me how can I go to the decalthon sport store in Shenzhen? by bus or subway? and the cost?

But what is your departing place? Anyway, here is some hints about its Shahe branch:
take local subway Luobao line to get off at Baishizhou Station. Then take a taxi to the Decathlon sport store at Shahe East Road. And local bus no. 54, 43, 26 or b681 can take u to European City, which is within walking distance from the store.
