Knowing means getting close to virtuous people who dare to speak. Wei Zhi is an outspoken mirror, so if someone dares to give you frank feedback in our life, you will have a reflection diary source to remind you where you are wrong, and your progress will be much faster.
Forgiveness is a tolerant, tolerant and trustworthy person. Charles Munger said that we should try our best to live in the network of trust. People who can tolerate others are broad-minded, from which we can be nourished by love and trust.

More information means that a well-informed person can help you broaden your horizons and expand your thinking.
Friends, direct friends, trusted friends, and friends who listen more are the friends worthy of our association.
