Jiu Si obviously has the ability of introspection and speculation. Gentlemen will go to Jiu Si so that they can find their own shortcomings and improve them.
Confucius said: "A gentleman has Jiu Si: he thinks clearly, listens attentively, looks respectfully, speaks loyally, thinks respectfully, asks doubtfully, and feels resentful." Confucius said: "A gentleman should think about nine things: seeing things and thinking about whether they grasp the essence, smelling things and thinking about them, behaving respectfully and speaking sincerely and frankly." Wait a series of questions, and use this sentence to speculate and introspect whenever you finish something.
It is very important whether you speak frankly and sincerely. If you speak sincerely, others will listen to you and be a team with you. If you are not sincere, you may be recognized, but after a long time, you will still be abandoned by them.
As you can see, what's the point of thinking when you see something? Now some people don't want anything from others, which makes others very embarrassed. Some parents don't like others to give gifts, and feel that they have money to buy and don't need others to give them at all.
Sometimes, this small gift contains friendship. If you refuse, do you also refuse this friendship? I usually send something out from time to time. On special days, I give others something to express my feelings for them, and they will gladly accept it. They will also give me something, a book, some toys or stationery as feedback. The significance of this is self-evident.
A gentleman has Jiu Si. This Jiu Si can make us think and reflect, and remind us all the time when we do things. We should remember this Jiu Si, and let's follow it to do things better.
