Let me try to make it more clear for foreigners,lol.
The whole sentence is "人生若只如初见,何事秋风悲画扇? "
If the whole life is like the first time (美丽的,惊艳的,fall in love at the first look)we met each other,how can later we argue, quarrel,separated even 抛弃. Sorry I didn't translate directly,because 画扇有个典故,女子被遗弃。
