Upper Buddhism: Pali upper seat. Thera, which means elder and seated, is the self-name of southern believers; Vàda means talking, talking, discussing and viewing. Buddhism was called "Southern Buddhism" in the lecture because it spread southward from Indian mainland to Sri Lanka and Myanmar. And because the Sanzang Classics are recited in Pali (pà? I-bhàsà), so it is also called "Bali Buddhism".

Seated Buddhism is based on the Eight Right Paths, and its teaching method is pure. Existing in Southeast Asia, Myanmar, Thailand, Sri Lanka, Cambodia, Laos, southern Vietnam, China and Yunnan border areas. It began to enter the western society in the early 20th century and the Chinese world in the 1980s. In Xishuangbanna, Dehong, Simao and Lincang, almost all Dai, Bulang and De 'ang people believe in Southern Buddhism, and some Wa people also believe in Southern Buddhism.

Shangbu Buddhism, which spread to the south, adheres to the original teaching method of respecting the world, only respects the three treasures of Buddha, Dharma and monk, recites and respects Sanzang's Dharma, Classics and Classics in Pali, and practices meditation according to the methods of eight saints, meditation and four thoughts. Most people are committed to getting rid of troubles, life and death, and achieving nirvana.

Seats are "conservatives" in Buddhism, and even the language used to record Buddhist scriptures dare not be changed at will. Pali was only an oral language in ancient India, and there was no independent writing of its own. When the Sanzang Sutra recited in Pali was introduced to Sri Lanka, the Biku people at that time recited it with great respect, forming the Sanzang Sutra recited in Pali. Since the first century BC, Sri Lankan elders have spelled Pali with Sinhalese (Sinhalese) letters and carved them on tàla patta, which has been preserved ever since. When Pali Scriptures were introduced to Myanmar, Thailand, Cambodia, Laos and other places, this tradition remained unchanged, and accordingly three Pali Scriptures transliterated in Burmese, Thai, Khmer, Lao and other letters appeared. Therefore, at present, the Buddhist disciples who are seated at the table all use Pali when reciting Buddhist scriptures. A sitting Buddhist monk must learn Pali besides knowing his own language. If there are Pali letters, these different versions of the classics can be restored to the original Pali characters. But the classics spread from India to Central Asia, China and Tibet are different, and they have all been translated into local languages.
