Is it okay to hang Mao Zedong’s paintings in stores and at home at the same time? Is it okay to hang the portrait of Mao Zedong at the same time as my home?

This is actually not that conflicting. It is that Feng Shui theory mainly focuses on peace of mind and just trying to go smoothly. It mainly depends on personal mentality and an open mind.

If you are really worried, ask a famous Feng Shui master to take a look.
