What if I tell others about my calculated life?

It doesn't matter if you tell others the fortune-telling results. Don't tell anyone your birthday casually. There are some witchcraft circulating in the Jianghu, that is, you can influence others or manipulate others with their birthdays, but the probability is very low, unless you have a deep hatred or offended someone, and someone deliberately messed you up.

Do more good deeds every day and accumulate more virtue. Don't worry about what others will do to yourself. A virtuous and good person will protect you in heaven. It is not difficult to accumulate virtue and do good. It's not difficult to start with daily chores, give others a kind smile and find ways to return what others have lost in time.
