Whose inscription is incense burner peak? In Xiangshan Park in Beijing

What we see now is a stone carving redone three or four years ago, inscribed by Liu Ruizhen, a famous calligrapher in China.

The original stele was marked with an altitude of 557 meters. A few years ago, the professional survey found that the altitude of Xianglu Peak should be 575 meters, so it was revised and now it is marked with an altitude of 575 meters. The original font was official script, but now it is regular script.
