it's harder than the chinese official language. for example it has 9 accents while the official language has just 4....
trust me, the official language is the easiest for u. in fact, this is why we make the official language like that....
it is simplified to allow the communication between chinese and foreigners easier.
however, we have to lose some very very special cultural phenomenon in the simplified language...
but if u need to learn hokkien for a job, u have no choice...
good luck
