Is there any problem with the ventilation of the guest room door, bathroom door and balcony door? How to solve these problems? Can installing a shower curtain in the middle of the toilet be solved?

Generally speaking, there is no problem. But when decorating, don't point the kitchen stove at the kitchen door: because the stove can't point to the door or balcony, you have three doors in one line. If the kitchen stove is facing the kitchen door, it is equivalent to facing the balcony, which is easy to make the hostess feel unwell, suffer from gastrointestinal diseases, headache and not accumulate wealth.
