The most important place to visit is this place, because it has a direct connection with the name of Phnom Penh. The legend of Tashan is that a mother-in-law named "Border" picked a hill made of earth to worship the Buddha statue floating from the Mekong River. In honor of the mother-in-law, he called it Phnom Penh, Phnom is the mountain, Penh is the name of the mother-in-law, so in Cambodian, Phnom Penh should mean "Bianpo Mountain". There is a Tashan Temple on the mountain, which serves multiple Buddha statues and statues of the mother-in-law. Tashan is not very high, so some people say that it is wrong to overlook Phnom Penh on it.
