狭路相逢勇者胜温柔只给意中人
[xiá lù xiāng féng yŏng zhĕ shèng wēn róu zhĭ jĭ yì zhōng rén]
It expresses an ancient proverb 'Xiá lù xiāng féng yǒng zhě shèng, wēnróu zhǐ gěi yìzhōngrén'. In the narrow way meeting bravery wins, kindness only gives to the destined person. It indicates facing challenges bravely but treating only your sweetheart lovingly. It’s a philosophy about how one should behave both tough and gentle under different situations.
