Hungry ghost festival is a combination of Taoism and Chinese traditional folk, the corresponding, mainly based on the same world view: heaven, earth, water, permeating the godhead into cheongwan, officer, officer of water permeating the governance by the government agency. Folk known as "three worlds", is in three officer refers to three of the gods.

Chinese eastern han dynasty last years, the documents has comprehensive Taoist cosmology, and before the first ever to be on the "three officer calligraphy", respectively, into the heaven, earth, water, and said to three officer sin, repentance to pray for peace. After the development of the six dynasties period, combined with the three days and three yuan in the tang dynasty to the promotion of the official, has, in the yuan, the yuan, and so on three ganjitsu standard, be blessed, najib, ancestor worship, three yuan festival to worship, the emperor rate officials to participate in the festival ceremony. After the tang, song, three ganjitsu become a folk festival.

The hungry ghost festival, daoist temples, such as outside the gates of fire temples, XiBianMen baiyunguan temple and so on in order to pray the good crop weather, peaceful country and safe people routinely held "blessing propitious dojo" every year. Because of the psychological fear him, people in the daily life of composite of Confucianism, Buddhism, Taoism, the lunar July 15 of the hungry ghost festival known as the ghost festival, called the lunar July "ghost month".

After the introduction of Buddhism, Buddhism also has a prayer ancestors, known as the "house," Lamar quin had gone words ULLAMBANA (India), namely "Meng Lan basin will". Meng Lan basin is the meaning of abuse, the pain of life is like a bat hangs on the tree, hanging, suffering. In order to make the living beings from suspension, then need to chant, cloth off food to the wandering soul wild ghost. The move coincided with the Chinese ghost month, worship, and Buddhism is the lunar July 15 turn undead will held on this day, so hungry ghost festival and Meng Lan will come down at the same time.

“中元”之名起于北魏，是道教的说法。根据古书记载：道经以正月十五是“上元”，为天官赐福日;七月十五是“中元”，为地官赦罪日;十月十五是“下元”，为水官解厄日。据《修行记》记载：“七月中元日，地官降下，定人间善恶，道士于是夜诵经，饿节囚徒亦得解脱。”因此，在七月十五日这一天，民间都会准备丰富的牲礼，祭拜地官大帝及祖先。

中元节是道教与中国传统民俗相结合的产物，二者能够相应，主要是基于同一宇宙观：即天、地、水三界，被神格化为天官、地官、水官所统辖的三界府署。民间通称的“三界公”，便是以三官泛指三界众神。

中国东汉末年，天师道便已综合前道教期的宇宙观，首过需上“三官手书”，分别投于天、地、水中，表示向三官忏悔罪过，以祈求平安。经历六朝时期的发展后，三会日与三元思想结合，在唐代官方的提倡下，上元、中元、下元等三元日定型化，成为祈福纳吉、祭祖拜神的三元节日，皇帝率百官参与节日仪式。唐、宋以后，三元日成为民俗节日。

中元节时，道教宫观，如地安门火神庙、西便门外白云观等为了祈祷“风调雨顺、国泰民安”每年照例举办“祈福吉祥道场”。因为惧厉的心理，民众于日常生活中复合儒、佛、道三教，将农历七月十五的中元节称为鬼节，称农历7月为“鬼月”。

佛教传入后，佛教中也有一种追荐祖先的超度仪式，称为“屋兰玛纳”(印度话ULLAMBANA)，也就是“孟兰盆会”。孟兰盆的意义是倒悬，人生的痛苦有如倒挂在树头上的蝙蝠，悬挂著、苦不堪言。为了使众生免於倒悬之苦，便需要诵经，布绝食物给孤魂野鬼。此举正好和中国的鬼月祭拜不谋而合，且佛教也是在农历七月十五这一天举行超度法会，因而中元节和孟兰会便同时流传下来。
