I am a small citizen, how could I do something earth-shattering? I am a piece of flying dust, how can I have thoughts of snowflakes floating in the window? I am a stream of water. Although I try my best to get close to the seedlings in the field, I cannot change the direction of the channel. Fortunately, I am a rainbow after the rain, and I like to decorate the clear sky by nature. Although it does not last long and lasts only for a short moment, I still feel that such a presentation is rare and worthwhile.
