Live in China, there are some rules that I have learned from my friends, my family, and my own experience.
Will continue to update this article.

Be asked for help

When a person asks for help, they are not only asking for a solution. They are asking for a companion to walk with them through the problem.

At that time, don't teach them how to solve the problem or how to avoid it. MUST NOT blame them.
They are already in a bad mood and a bad situation. It will only cause the conflict.

Be with them. Listen to them. Ask them questions. Help them to think about the problem.

Don't say "I know how to solve it." Instead say "I am here with you."

Say less maybe, should, probably

be powerful
be decisive
deliver the confidence.

Don't answer a question with a question

When someone asks you a question, they are looking for an answer. They are not looking for another question.

Please just say the answer.
Don't say "What do you think?"

Stop loss in time

I have wasted a lot of time and money in my life.
At the beginning, I found some bad signals.
But I think it will be better and I put more energy in it.
Finally, I lost more.

Sunk costs are no longer relevant to future rational decision-making.
When you find the bad signals, stop loss in time.

Don't say I think

prove them

not only give the direction, but also tell them reasons

not only give the direction, but also tell them reasons
let them know why they should do this

Providing excuses

It sounds a bit abnormal.
We are often taught not to make excuses.

Chinese are implicit. Sometimes they need excuses to do something.

Support, not Preaching

Someone shared their idea to you.
Ask you if it's a good idea.
If it's not an obvious mistake, let them try it.
