Is the eight characters in charge of people's destiny or the appearance in charge of people's destiny?

Eight characters and looks are actually the same thing.

The eight characters refer to the innate part of human beings, strictly speaking, only accounting for 50% of the composition, and the acquired half, which is what the ancients said: one life, two luck, three feng shui, four virtues. Life cannot be changed, but luck can control it. If you work hard, you will surely achieve greater success. Feng shui can be adjusted and named the day after tomorrow. Try to have a name that matches the eight characters, and then do more good deeds. This will definitely change your destiny.

Looks the same. Do more good deeds and try to change your own shortcomings, and your appearance will change.
