^^ wow..then may I ask..why they use li instead of lu?? why there are so many diffrent Hokkien tone?? I keep on wondering for this few years hehe..
Experts from China had explained about this .At first the vowel is lir,tir=lw,tw in cuanciu.Then it became li,ti in ciangciu. u sound appeared in xiamen not long ago.
I can email two articles to you.
I have an article by Prof.Chiu saying tainan is hueh
Two sects in ciangciu 平和 and 华安 is huih like cuanciu.
Don't forget that we also have ciangciu sects in 安溪 china as well.
