This is the case in today's society. If you can't change by one person's strength, you can only change yourself, so how should you change? The first is wit, which is a compulsory course in life. If you are not smooth enough, you will only get hurt more and more, and finally arm yourself like a hedgehog. After that, you must have a mind's eye. To put it bluntly, it is scheming. The sinister rivers and lakes mentioned in martial arts novels are also a portrayal of our society now. However, I hope you can learn from it and go your own way. Don't change yourself and let yourself lose your original heart.
