You can unfold the bag for the first time, and you can unfold it in a gang. If it is expanded in the future, it seems that buying 6.6 yuan in the district mall can expand it five times.

As for the warehouse, it can also be expanded, but it seems to be 1 100 to go to Fuyuan Pavilion to exchange the hoarding order in Fuyuan District.

I hope this helps.
