爱只有简单笔画
[ài zhĭ yŏu jiăn dān bĭ huà]
Love can be simply sketched in a few strokes here means that real love does not need to be complicated; rather it can be presented clearly with just simple lines (in Chinese characters, 笔画 (bǐ huà) means stroke count, which describes characters as simple with less strokes).
