You can make friends with colleagues at work, but colleagues should learn to observe who can be friends and who can only be colleagues.

Colleagues can't be friends without talking about everything, especially the gossip in the company and the gossip of the leaders.

You can introduce local villagers through classmates and relatives, and gradually find that you can become friends, and friends of friends can also become friends! Walking more, eating together, shopping and traveling have gradually deepened the relationship.
