Is GUCCI cheaper or more expensive in Hongkong than in Chinese mainland?

A survey shows that brand-name fashion is the first choice for Shenzhen people to go shopping in Hong Kong. GUCCI, Armani and other brands are usually not discounted in Shenzhen, and the price may be too high to see, but Hong Kong is different. In Hong Kong, if you don't watch it, you will regret it. There will be a big discount in case of changing seasons and around Christmas, because it is tax-free.
