No Door For Bed Room!!!?

N and M

Don't worry
Original is "Door not installed at time of O.P."
O.P. stands for occuption permit i.e. 入 伙 紙
Another document is 滿 意 紙 (Certificate of Compliance)
As O.P. is already done all doors should be installed (or installing)
So you can see the bedroom doors in most photo.
