First, the official store of Double Happiness, this is absolutely correct. But things should be safe. If this store is not real, then Taobao will not open any official XX store. Taobao should be closed, too.

Second, anti-counterfeiting and upgrading, which I really don't know. I just bought a pair of erasers, but I didn't bother to look them up when I saw the security code.

Third, Dongdong with a price of 100 yuan can't come to this official XX store. Please feel free to use.
