Your "nine region culture village" is Formosan Aboriginal Culture Village? If so, that's in Sun Moon Lake and the One Piece event is inside the village.

On top of that, the One Piece event thingy is ending on 30th June.

1/8 will be very rush depending what time u travel from taipei to taichung with the hsr. take 1 or 1.5 hr i kinda forgot assumiing the ninge region culture village is the formosan aboriginal cultural village. this place is near sun moon lake. taichung to sun moon lake takes quite a distance. sun moon lake to this village also quite a distance. assuming u stay at sun moon lake? next day going one piece theme park which is the same village again?
april should be a good month for shopping. no more winter clothing specially end of april
another month will be oct if i remember correctly

hmm..thanks all sifu for reply..this is when i m in tai zhung i willl be staying near to feng jia night market..I m still very confusing for these 2 days..I will be leaving tai pei early morning on 1/8 then take HSR go tai zhung..i think time will be sufficient if i leave early morning right ?
