I've been thinking about it for a long time but haven't come up with a satisfactory introduction. Today I accidentally chatted with someone, and suddenly I just wanted to leave a sentence here: If you are used to bitter coffee, too many sour lemons, and tired of drinking sweet milk tea, you are welcome to come to my place for a cup of boiled water, which is not too cold or too hot.
Purpose: Right and wrong, good and evil, are not determined by one's origin.
