Buddhism is full of worldly things, trivial things and chores. How to cultivate self-cultivation and character?

When dealing with all kinds of things, just follow the six degrees of Buddhism! For example, when cooking, we should make it clean and delicious for everyone to eat, so that everyone can eat healthily and happily. When cleaning, clean up, don't affect others, and then let everyone live in a clean, beautiful and healthy environment. When dealing with all kinds of people, we should give alms, keep precepts, endure humiliation, be diligent in meditation and wisdom. Specifically, do not fight for fame and fortune, be patient and tolerant, be generous and kind, persist in kindness, do not hit people or quarrel, and be aboveboard. This basically includes the Bodhisattva's six-degree walk.

My humble opinion is for reference only.
