What is the meaning of "Suzaku must use the Phoenix symbol system" in the Yellow Calendar?

Suzaku belongs to the south fire, because it is on auspicious days and windy waters of the ecliptic. When choosing a date, if you must be on Suzaku Day, you must use the Phoenix symbol system. Generally, when going to a temple (Taoist temple), please wear a phoenix symbol, or ask the mage to draw a phoenix symbol to wear. So you can do things on Suzaku Day.
