Ask the height of the master's tomb.

It is reasonable to allow the boss to be taller, which has nothing to do with this. The height of the tomb is not a concept. The tomb is expensive in the mountain boundary for the benefit of future generations. The height is usually based on the mountain in front, and the water below the mountain is not bounded. The head-on wind is much higher than the mountain, so it is not good to hide the wind and gather gas, and the incense is easy to be blown away by the wind. The tomb is only a little higher than the mountain. As long as the location of the tomb is high and low, the effect of gathering wind and gas in front of the mountain boundary is good, and it is not conducive to family unity without arguing about who is the eldest and who is the second. Geography should also consider human factors, which is to serve people.
