#im crying at the club as soon as they mentioned baozi shop i immediately knew which scene they were talking about in the last season

Regarding the pun, they haven't revealed the name of the baozi shop, but I can take a few wild guesses:

Open all year round is 全年无休 Quan Nian Wu Xiu

权莲无休 Quan Lian Wu Xiu - Ah Quan and Huilian never end. This one combines their name together.

权莲无休 Kyun Lin Mou Yau - The same one as above, but if read in Cantonese, Wu Xiu becomes Mou4 Yau1 which is the same as 无忧 Mou4 Yau1 and it means free from worries. It'll become Ah Quan and Huilian free from worries.

权莲误消 Quan Lian Wu Xiao - The misunderstanding between Ah Quan and Huilian's disappears.

权恋无休 Quan Lian Wu Xiu - Never stop loving Ah Quan.

These are my guesses. If anyone has any other ideas, feel free to let me know, and I'll add them to the post. Or, if they reveal the actual name next week, I'll edit it with the new explanation.

Edit: They haven't revealed it in the show, but AHA Entertainment posted a video on their Wechat with '权莲无休' 'Quan Lian Wu Xiu' in the caption.
