Guan Yu is also worshipped as a door god in Chinese and Taoist temples, with portraits of him being pasted on doors to ward off evil spirits, usually in pairings with Zhang Fei, Guan Ping, Guan Sheng or Zhou Cang. Apart from general worship, Guan Yu is also commemorated in China with colossal statues such as the 1,320-tonne sculpture in Jingzhou City, Hubei Province, standing at 58 metres. Guan Yu is revered as "Holy Ruler Deity Guan" () and a leading subduer of demons in Taoism. Taoist worship of Guan Yu began during the Song dynasty. Legend has it that during the second decade of the 12th century, the saltwater lake in present-day Xiezhou County gradually ceased to yield salt. Emperor Huizong then summoned Zhang Jixian (), a 30th-generation descendant of Zhang Daoling, to investigate the cause. The emperor was told that the disruption was the work of Chi You, a deity of war. Zhang Jixian then recruited the help of Guan Yu, who battled Chi You over the lake and triumphed, whereupon the lake resumed salt production. Emperor Huizong then bestowed upon Guan Yu the title "Immortal of Chongning" (), formally introducing the latter as a deity into Taoism. In the early Ming dynasty, the 42nd Celestial Master, Zhang Zhengchang (), recorded the incident in his book "Lineage of the Han Celestial Masters" (), the first Taoist classic to affirm the legend. Today, Taoist practices are predominant in Guan Yu worship. Many temples dedicated to Guan Yu, including the Emperor Guan Temple in Xiezhou County, show heavy Taoist influence. Every year, on the 24th day of the sixth month on the lunar calendar (Guan Yu's birthday in legend), a street parade in Guan Yu's honour would also be held. In Chinese Buddhism, Guan Yu is revered by most practising Buddhists as Sangharama Bodhisattva () a heavenly protector of the Buddhist dharma. "Sangharama" in Sanskrit means 'community garden' ("sangha", community + "arama", garden) and thus 'monastery'. The term "Sangharama" also refer to the dharmapala class of devas and spirits assigned to guard the Buddhist monastery, the dharma, and the faith itself. Over time and as an act of syncreticism, Guan Yu was seen as the representative guardian of the temple and the garden in which it stands.
