Excuse me, does Huang Wu change its position in the solar or lunar calendar every year?

It is neither solar nor lunar. Fengshui fortune telling uses the summer calendar, which has been used for thousands of years. Generally speaking, 24 solar terms, such as beginning of spring and winter solstice, are actually summer calendars.

Beginning of spring Day is the dividing line of a year in the summer calendar, and the neutral spring day in the solar calendar usually falls on February 4th, sometimes on February 5th.

Therefore, the fleeting time can be said to have changed that day in beginning of spring. But sometimes, the fulfillment of Shaqi will be earlier. So it's best to choose a day before beginning of spring, and choose an auspicious day to arrange the settlement.

According to the theory of flying stars, in 20 15, three stars entered the palace, and the flying stars flew smoothly in the fleeting time, so two black stars would fly to the southeast.
