Doing things well and roundly is an attitude towards life that everyone should learn. I will analyze this sentence according to my own experience and understanding.

When you do something for others or yourself, you want it because it is square. Because we have to be angular and know where the point is. Besides, in order to do this, you can't compromise easily. When you decide to do it well, you must be square and meticulous.

You can't do things tactfully, because many times things themselves have a very standardized result. If things die, people live. If you want to do things smoothly. Then, the final result you pursue must be very smooth, and you may not be able to catch it if you want to. When you do something, you ask the party, because it must be able to put it down smoothly.

Round is because man is the most complex animal in the world, mainly because he has complex psychological activities and emotions, and you will never guess which direction it will develop.

Therefore, tact is to leave you with corresponding performance space in interpersonal relationships. You need to deal with people from all walks of life. In this process, you must know what can and cannot be said, what can and cannot be done.

And in this process, you can't just let others see through you. In fact, from a certain point of view, tact is also a manifestation of high emotional intelligence. A group of people will always have some contradictions in the process of communication. The people who can really mediate contradictions are often those who are smooth.
