Speak with Restraint, Act with Measure, Work with Abundance, and Speak with Virtue
A person's behavior reflects their upbringing and quality; no matter how much your appearance is packaged, the inner things will still be revealed through behavior.
There are boundaries to speech
As the ancients said, 'A warm winter three sentences, the language is also an art.'
Everyone has their own self-esteem and pride, don't challenge others' temper with your own personality.
Learn to be respectful, make others comfortable, is the highest level of a person's manners.
'Being good' doesn't mean 'you can say anything'; 'being angry' doesn't mean 'you can't afford to joke'; 'I didn't do it on purpose' doesn't mean 'you're not wrong'; 'I have no ill intentions' doesn't mean 'I haven't caused harm.'
When speaking, think from multiple perspectives, think about your position. Sometimes, a seemingly understated accusation can be the last straw that crushes emotions; a seemingly playful comment could be the domino effect.

You don't know what others have experienced, don't judge what you see.
There is a scale to speech; it is a person's high cultivation, a person's maturity, reflects a person's life level, and reflects a person's life level.
Always be mindful of the scale of your words, pay attention to the occasion, identity, and conversation object, in order to let words reach the most appropriate scale.
Everyone has difficulties, appearances are all rooted in reality. Less sharpness in words, more leeway, is kindness to others, and respect for oneself.
Playful humor
Jokes are a very common and ordinary thing in daily life, but the purpose of jokes is to adjust the atmosphere; if you don't know how to grasp the scale of jokes, words will unintentionally harm others.
Marshall Rosenberg said: 'Perhaps we don't think our way of talking is violent, but language often causes pain to ourselves and others.'
A person's sense of proportion when joking often shows their character.
Don't make fun of others' shortcomings, don't make fun of others' privacy, and don't make fun of others' life.

True humor is not a show of boisterous jokes, but to create a pleasant atmosphere at the right time and in the right place with appropriate words.
Understanding and respecting others can make the feeling of jokes just right, like a spring breeze.
Only if the other person finds it funny, is it a joke; if the other person finds it unpleasant or angry, that's impolite.

Doing things with abundance
As the ancients said, 'Leave a line for future meetings.'
In life, ups and downs, highs and lows, it is inevitable to be proud and inevitable to be low. When proud, treat others well; when down, treat yourself well.
Many things are unpredictable, thirty years of East, thirty years of West.
No matter when and where, don't say too much, don't do things too forcefully. If you don't leave a little leeway today, you'll have a tongue to lick; tomorrow, the peak will turn and the narrow road will meet, inevitably adding embarrassment and harm.
Give others a little space, also leave yourself a way out.

Speech has virtue
As the ancients said, 'A sharp blade cuts the body, and it's easy to combine; evil words harm people, and hatred can't be eliminated.'
Before speaking, you'd better think it over, don't just pursue your own quick words, but disregard others' feelings. Words spoken are like water splashed.
Don't think that saying 'don't take it to heart' can make others think you said nothing. In fact, no matter how you remind others 'don't take it to heart,' others will still feel that you've exposed your most true thoughts.
