One view is that photos of married children should be posted on the east wall, because the sun rises in the east, which means family harmony and unity, and children will become more and more distinguished. And if you stick it on the western wall, the photo may be discolored by the sun.
Another view is that photos of married children can be posted on the Western Wall, as long as they don't face the west. The orientation of the photo wall should be determined according to the specific housing layout and sunshine conditions, and it cannot be generalized.
Therefore, whether to post photos of married children on the Western Wall still needs to consider the specific actual situation and the balance between personal morality and photo maintenance.
