Mysterious tomb in the valley

This mysterious tomb resides in the valley of Baiwang hill. It has been known to me for some years. During a tour to the hill on Oct 12, we visited the tomb again. First image showed this tomb has a curious "front gate", built with piled stones, stands firm. A white object can be seen on the left, which is the gravestone been pushed down from its original place. Second image is about it. First part of it is in a language I didn't recognize, but I guess it said the person buried there was born on September 1877, and died 1947. Second part is in Chinese, but most contents had been removed with great strength, obviously intentionally, as though someone didn't wish to let the contents been read by others.

A lot of local residents were strolling there all the time, but seemed no one cared about it.
