What kind of state is it not to rejoice in things, not to grieve for yourself?

From Fan Zhongyan's Yueyang Tower. The external meaning of this sentence is not pride and ecstasy because of the richness and wealth of foreign things; It's not because of personal frustration. It means to maintain a constant indifferent attitude regardless of success or failure, not to sell yourself short because of temporary success or failure, and to maintain an open-minded and indifferent attitude at all times.

It is China's traditional Confucian thought not to rejoice in things, not to grieve for oneself, and to pay attention to inaction. It is a kind of ideological realm, and it is also the requirement of ancient literati's self-cultivation.

There are roads in the world that can't be crossed and mountains that can't be crossed. It is a kind of wisdom to choose to turn around calmly when encountering a mountain that can't be turned over. Don't be happy with things, don't be sad for yourself, stabilize your mind, don't be influenced by the outside world, don't be overly happy about temporary "gains", and don't worry about temporary "losses". You know, everything has its own rules. I hope everyone can treat their future with the mentality of "not being happy with things, not being sad for themselves".
