Guo'en Temple was originally named Bao'en Temple. It was built by Huineng, the sixth ancestor of Zen Buddhism, to repay his parents for their upbringing. Later, Wu Zetian granted it the name Guo'en Temple. The temple is located at the Dragon Head of Longshan Mountain, and was also called Longshan Temple in ancient times. There is a Tang Dynasty memorial archway in the temple, with the words "First Place" written on it. Next to the temple are the "Parents' Tomb" and the "Bao'en Pagoda" as well as the litchi tree planted by the sixth ancestor Huineng, which has been more than a thousand years old. The first hall in the temple is the "Dharma Guardian Hall", where the Sixth Patriarch's Altar Sutra prayer wheel is turned, and Shenxiu and Fahai are enshrined on the left and right to honor the two for their merits in protecting the sutra. There are five white marble steles behind the Heavenly King Hall. The one in the middle is the imperial edict of Wu Zetian in those days, and the other four inscriptions are written by Liu Zongyuan, Wang Wei, and Liu Yuxi. The temple opens at 8 am, so you don't have to go too early.
