The Confucian Temple in Hanoi, Vietnam, was built in 1070 under the auspices of Li Shengzong, the emperor of the Li Dynasty who advocated Chinese Confucianism. It has a history of nearly ten centuries. Confucian temples are mainly used to worship Zhou Gong and Confucius as well as Sipai and 72 sages. All the descendants of Royal relatives and relatives study here. Hanoi Confucian Temple sits in the north and faces the south, covering an area of more than 26,000 square meters. It is said that the pattern of the Confucian Temple was modeled on that of the Confucian Temple in Qufu, China. There are five elements in the courtyard around Hanoi Confucian Temple, representing the five elements of Chinese culture "water, wood, fire, gold and earth" and "benevolence, righteousness, courtesy, wisdom and faith". Hanoi Temple is the third most important cultural relic protection unit in Vietnam after Ancient Luocheng and Shunhua Ancient Capital. The Confucian Temple Gate is divided into three portals, the middle gate is divided into two layers, the upper and lower, written in regular scripts in Chinese characters "Confucian Temple Gate". The middle door only opens when the emperor conducts sacrificial activities to Confucius or makes a list of imperial examinations. Usually it only opens the left and right side doors. The only difference between Hanoi Confucian Temple in Vietnam and Confucian Temple in China is that there are more palaces behind Dacheng Hall dedicated to Zhu Wenan, a master of Confucianism in Vietnam. He has made great contributions to the development of Confucianism in Vietnam, and his status is equal to that of Zhu Zi in China. There are also two key secondary schools in Hanoi, named Wen'an Middle School. After hundreds of years of wind and rain, Guozijian now has only one street name and nothing else. The Confucian Temple has been renovated and opened to the outside world, making it one of the most important tourist attractions in Hanoi. Every year during the Spring Festival, Hanoi Municipal Bureau of Culture holds a grand ceremony of sacrificing Confucius in the Temple, including ceremonies, painting and calligraphy exhibitions, chess competitions and other cultural activities, attracting a large number of visitors to watch.
