If you go to Ahom Museums you will often find a canine-like figure head being called as Ngi Ngao Kham and even so-called Ahom history experts like Nobin Buragohain have made tons of videos fooling their audience about this entirely fake misappropriation and misapplication of a word

The Early Ahom Movement

In the 1970-80s Ahom grandpas were struggling with their new Ahom movement. First they didn’t know any Tai and second they didn’t have any flag. There was some knowledge about the serpent figures and Ahom chimera/dragon like emblem which was used throughout coins, inscriptions, etc. but no one knew what it was called (the Assamese people just called it singha). So they read Ahom Buranjis (1930)^[1], and in the very first chapter (compiled from Deo Buranji / Pvn Ko Mvng) they found a neat little story of the youngest son of God, Ngi Ngao Kham also called as Phura and Voila ! They not just found a Tai sounding name for this figure, but also a certain history to ascribe to this. Thus the emblem was called Ngi Ngao Kham and the flag became ‘Khring Fra’

The manuscript from where this is taken is dated 18th CE^[2] so I believe this myth couldn't have been invented before 17th century. And yes I am saying invented because this is not a generic Tai myth unlike the story of Khun Lung Khun Lai or Möng Ri Möng Ram. Infact there are no characters like Lengdon, Yasengfa, Ailaengdin, etc among other Tai people. We can draw many conclusions from this, either the Ahom priests were inspired by Hinduism or they were trying to tackle Hinduism by making their own Ahom Gods in line with Hindu Pantheon. For eg., the Bamuns had also called Ahoms as descendant of Indra and "low-caste" Shyam / Shan woman so they may have created Tai version of Indra (Lengdon) to stop Ahom Kings from forgetting their Tai heritage.

Whatever be the case, but this story of Ngi Ngao Kham is found only among Ahom. And the word Phura/Phra comes from Pali word vara meaning top, noble or excellent which can be used in many contexts – Buddhist Tais use it for Buddha, Christian Tais use it for Jesus, but Ahom Animism is idol-less. Even the neo-Gods like Lengdon etc are still thought of as higher-ranking spirits and thus do not have any idol. Hence calling this mythical animal as Ngi Ngao Kham is not just historical misappropriation but also a violation of Dai Animist traditions of making an idol of a godly spirit. Another word 'khring fra' or khing phura is also a clear misomner when used for flag. In manuscript context put khing phura means who will succeed Phra (God) but as a word for flag this term is wrong, as the word for flag is làam which is a Burmese-loanword as Tai doesn't have native word for flag. This thing was pointed by B.J Terwiel^[3] as well

Meaning of Ngi Ngao Kham

Word Breakdown - ngí means a deer, ngāo means shade, luster or radiance, and xám means gold. So Ngí Ngāo Xám means the deer of golden shade (or golden luster or golden radiance). Lot of historical Dai Ahom persons, have had such names from deer, like La Ngí - deer (the childhood name of Serpatfa / Gadadhar Singha), and military officers like La Ngi Kham, La Ngi Khern, etc. For more information you can check the article on historical Ahom names

There can be a slight debate ignited by some people here that ngi should be translated as youngest son^[4], which is the meaning given in Bar Amra. Now this is one of the case where I think Bar Amra is wrong. Because youngest child is actually lúen and ngī is actually affix for second son. And even if you believe otherwise, that still doesn’t explain away that this word still has nothing to do with the insignia. So what is the real name of the insignia even?

Pyinsarupa (ပဉ္စရူပ)

Pyinsarupa is a chimeric mythical animal from Burmese mythology. The Ahoms (Shans) and Burmese had very close relationship and during their cultural exchange this figure became part of Dai Ahom culture, infact this figure is used in Eastern Shan and Lanna culture too. One of its constituents, the Tonaya (တိုးနရား) or leo-dragon is re-hashed as a Himalayan deer-like figure (တူဝ်း) used for the famous Dai deer dance

Luang / Lóng 龍

Phaya Luang, or Luang Len Fa (ลวงเหล้นฝ้า), or sometimes simply Luang (ลวง) is Dai Lue dragon very close to Pyinsarupa, infact almost same. The word Luang comes from Chinese word Lóng 龍 for dragon, because there is no native Tai word for dragon.

Luang Len Fa (literally the dragon playing in the clouds) is regarded as noble creature by the Dai Lue people. There is a belief that Luang comes to bless people in the area of well-being ^[5]. Now, Dai Lue is one of the closest to Dai Ahom, infact it is believed that Möng Ri Möng Ram (literally wide and depopulated country) refers to Xishuangbanna region of Yunnan where the Dai Lue people live. Hence, the actual word for this figure is NOT "Ngi Ngao Kham" but Long Lēn Fā or simply Long

Note that Ahom doesn't have the -ua vowel and it's not even needed. We can simply say Long in rising tone same as Chinese.

Remember: Long Lēn Fā not Ngi Ngao Kham !
