《增广贤文·上集》
人生在世，总会遇到各种挫折，要想有一千个好日子是很难的；就像花儿一样，它的美不能持久，最久也不过百日。黄蜂的针很毒，橘子都会分为两半。
人无千日好，花无百日红。黄蜂一口针，橘子两边分。
In life, we encounter various setbacks, it is hard to have a thousand good days; just like flowers, their beauty cannot last, at most a hundred days. The yellow wasp's stinger is very poisonous, even an orange can be split into two.
