Why Changping District is better than Tongzhou District? Please elaborate.

There is no question of being good or not. It's just that Tongzhou is close to Beijing, and people in the city move more. Now the population density of Tongzhou is too high, and Tongzhou is not as big as Changping. Changping is the back garden of Beijing, and it is also the upper outlet, so if the air in Changping is good, the air in downtown Beijing is good, and the feng shui in Changping is good, otherwise the thirteen emperors of the Ming Dynasty will not put their graves there. But Changping has a large population now.
