There are really too many fakes on the market now. When buying, you must find some reliable sellers, don't be greedy for cheap and lose money. Good choice and good service. There is really no reason to return it. That's a good idea. Search the Wan Wen store near your home and hope the landlord will adopt it! Also, ask this thing not to blindly follow the trend in the early stage. You should read more books, ask more questions and check more, and then buy. Wan Wen has a deep market, so expensive is not necessarily good.
