Which Taoist saint's Dojo is Louguantai?

Loutai was named after the Western Zhou Dynasty in 1 1 century BC. According to legend, the doctor of the Western Zhou Dynasty told Yin to take grass as the building, watch the celestial phenomena at night, see the purple gas coming from the east, and know that there will be real people passing by. Later, as expected, Lao Tzu went west to enter the customs and was greeted by Yin Xiying. Laozi wrote 5,000 words of Tao Te Ching here, and set up a platform in Gaogang, south of Lounan to teach the classics, leaving a name for himself.
