The Panda Street Instance had everything that the old Shop Instance had, only more compartmentalised since they had been broken into shophouses for people to mingle around. Jin had utilised the very same concept he first used when he opened his shop.
While it might look like small shophouses from afar, it was a different experience once they walked into the store as the area widened within the shophouses. This allowed groups of people to come in without an issue and would expand accordingly.
For example, the Bai Twin's Weaponry and Armoury Store Instances had been incorporated into multiple shophouses. Bai Wan had separated his shop based on the type of weapons being sold. Melee weapons had one store dedicated to them while the ranged items were another. He later further separated them based on the types sold.
