Take a step back and let yourself be at peace. Being tolerant is not about being afraid of others, and being tolerant is not about being weak. After all, there is no perfect thing in the world like a sweet melon and a bitter pedicle!
Life is a drama, we get together because of fate. Being together among more than 6 billion people is destined to happen! Why worry about little things?
No one is a saint, how can anyone have no faults? Even sages will inevitably make mistakes. Be tolerant and think from other people's perspective!
Confucius said: If a person does not know and is not stunned, is he not a gentleman? The prime minister's belly can hold a boat! A dignified gentleman must learn to be able to bend and stretch. If you can't care less about trivial matters, how can you deter the world in the future?
