Flowers are not flowers, mist is not mist, midnight comes and dawn goes. It comes like a spring dream, but it goes away like a morning cloud with nowhere to go. This is a poem that I like very much. Many things, if not cherished, will pass away and be regretted. I have written many times to write something, but I was afraid that I could not write well. I hesitated again and again and missed it. There will be no leisure time in another year, so I took the opportunity to write down what I thought to commemorate this period of lazy and decadent life.
