There is a big difference. For example, if you buy a diamond ring, the situation in a franchise store is that when you buy it, he will tell you that any store can adjust, clean and renovate the ring. But this is not the case. If you buy a ring in Liu Fu, Liwan District, and you go to Liu Fu, Baiyun District, their clerk won't accept it for you, because you didn't buy it in their store. But direct stores won't. Diamonds bought by diamond families all over the country can enjoy the same after-sales service, including exchange service. This is the difference.
