What does the fortune teller mean by avoiding the stars?

Avoid the stars, some places are called back to the stars, back to the stars, one meaning. The fortune teller will tell you the exact date. On this day, don't go out, don't answer the phone, and don't let outsiders visit. (My family can see it) Just shut the door for a day like Zhang Sanfeng! Legend has it that disaster reduction and refuge can be achieved.
