How should the initial consonant n be pronounced?

The initial consonant n is pronounced like the English consonant [n], which has been confirmed at the "Beijing Olympics" and the "Year of the Ox Spring Festival Gala". Such as "you, bird, cow, year". However, I don’t know how to pronounce n in Xinhua Dictionary? Among them, "Your Year of the Bird and Ox" is pronounced [n] correctly. However, the initial consonant of "that na na nan breast nai bag nang nao can nen serf nu coward nuo..." also has an n? Isn't it true that one initial consonant has two sounds? This is a strange thing that is "common". Otherwise, na, nan, nai, nang, ... should read "ya'an aian...". This is traditional Chinese. It is because the pronunciation of the initial n consonant [n] is not correctly established, so I no (not my local dialect, the Mandarin in Hong Kong, Sichuan, Shaanxi and before liberation) is pronounced as wo. This is the "popular" sound. . Because there is no [n], "An, Ao, Ai, Ang..." all have no initial consonants (except for a few pure sound and pure rhyme syllables, traditional Chinese generally has complete rhymes), so "Xi'an becomes an immortal" High walls" joke. Because there is no [n], hard nen becomes "yin", and yiyini becomes "meaning". So how should n be pronounced? I think, n must and can only read [n]. It can be spelled into syllables with almost all vowels except the u series (n and u cannot be spelled together, the initial consonant of slave should be l, and female is made up of n and iu (rain)). You cannot read both [n] and l. "Then it's impossible for the milk bag to cause trouble for the peasants and Nuo slaves..." can only use l as the initial consonant. For example, "nu donkey" is pronounced lu, "nanlang" is pronounced lang, "nanlan" is pronounced lan...
