"Dragon" or "loong"

Perhaps you might rephrase the question. I don't understand what you are asking, though someone else might.

What the hell is a "loong" supposed to be?

Something of good length in Glasgow.

It were a loooooong time before i got me key in the door.

Loong is not an English word (whereas dragon is). Loong is Chinese and as such, most of the audience here are not speakers of any dialect of Chinese so we're in the dark.

I just looked it up and found the following:
"Loong is spiritually linked to the Chinese and highly regarded as the Chinese nation symbol. Chinese are proud of been called "descendants of Loong".

Mythical creatures portrayed in ancient Chinese culture, with head of a horse, horns of a deer, ears of cattle, body of a snake, scales of a carp, claws of a hawk, palms of a tiger, with whiskers and beard but NO wings, capable of altering itself in size, length and color . Highly mobile in water as well as among clouds. It is generally regarded as benevolent and the source of rain, thunder and lightning. "

Why would a Chinese student some to a web site primarily inhabited by English speaking people to learn about obscure aspects of his own culture? It passeth understanding.
