I have been thinking about it for a long time, and many experiences have contributed to it, and it has begun to brew. This is a favorable way for me to have fun and learn something. From the beginning today, the work needs time, just to express my small feelings. If I don't do it now, I may not have the chance to do it in the future. The work needs to rely on experience and imagination. Experience brings thinking, and imagination is the source. It is regarded as a hobby and a place for learning.
