Phayao is the muang on the lake at the head of the Ing, by tradition a cadet foundation of the Ngoenyang house and in practice its own place.
The Phayao Chronicle says Chomtham reorganised the muang into twelve or thirty-six panna. Ngammueang, the ruler the Sukhothai inscription names as Mangrai's friend, belongs to the second half of the thirteenth century; who sat at Phayao in 1200 the versions do not agree.

Where the sources disagree
- English Wikipedia (Ngoenyang infobox): Phayao seceded in 1094. The Phayao article says the 1094 date is not in its source and the sources run from 1037 to 1131. Not used.
Evidence: Phayao Chronicle versions (undated compilation) and the Ngoenyang chronicles; the first attested ruler is Ngammueang, in the 1250s to 1290s.
On the map: A seeds drawing; the Ing valley is in the realm record as claimed.
Primary sources for Ngoenyang
Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.
- The later Tai, Lao and Mon chronicles of the north, Ratanapanna (Jinakalamali); Bodhiramsi (Chamadevivamsa); anonymous monks and court scribes (the Chamadevivamsa about 1410; the Jinakalamali 1516 to 1528; the Chiang Mai Chronicle in its surviving form 1827; the Nithan Khun Borom 16th to 17th century). There is no text of 1200 for the Mon kingdom of Haripunjaya, the Tai muang of Ngoenyang (Chiang Saen), Chiang Rung, the Yom and Nan valleys, or the Lao middle Mekong.
