法海若懂爱还有许仙什么事
[fă hăi ruò dŏng ài hái yŏu xŭ xiān shén me shì]
'If Fahai understood love, what trouble would Xusien be in?' This refers to a famous Chinese legend 'The Legend of the White Snake.' Fahai (a monk) doesn't comprehend the true essence of love which caused troubles to Xu Xian. Here it means when one understands true feelings deeply, unnecessary interference or misunderstanding will not arise anymore.
