We all have very tired tired, please remember that the long insist, can bring us the most permanent happiness. more will become the medicine of happiness!ni

we all go through entire exhaustion sometimes,but please keep in mind that the most ceaseless persistence can bring us the most permanent happiness.楼主，后面的这句“越是忍住泪水，越会变成幸福的良药。 ”主语是什么？我搞不懂，难以翻译。 我改成这样吧，Try hard to keep back(or stifle)your tear then it will become the key to happiness.
