Stores in Guangzhou and Shanghai

Hi friends, last time I went to Taiwan I found some great recommendations for stores from this community (Jelly Sport, addresses for official Yonex/Victor) but this time around I have been having trouble finding info for good stores to buy rackets in Guangzhou and Shanghai.

From what I have found so far it's just the flagship Yonex store in Shanghai which seems to carry pricey things. Any other recommendations? Looking for Yonex and Victor only

Only found 15+ year old threads on badmintoncentral and too difficult to navigate badmintoncn :(
