There is indeed a term for "Huagai" in fortune-telling, but it is definitely not good luck.
According to the horoscope, people generally have eight steps of great fortune, one every ten years. Of course, everyone's departure time is different. The latest delivery time is 10 years old. So what is the luck of people having sex? Any luck with Huagai? In fact, luck is based on the creation and restraint of the five elements and the five relationships between oneself (self, the one who gives birth to me, the one who gives birth to me, the one who restrains me, the one who restrains me), and then combines the combination of yin and yang to form ten relationships. They are collectively called the Ten Gods, specifically as follows: Zhengyin, Pianyin, Zhengguan, Pianguan, Zhengcai, Piancai, Food God, Shangguan, Bijian, Jiecai. Therefore, it is impossible to transport it to Huagai.
In fact, in numerology, Huagai refers to auspicious stars and evil stars, such as the nobles of Tianyi, the nobles of Wenchang, the gods of death, etc. A brief explanation of the Huagai star is as follows:
The Huagai star is shaped like a treasure cover. The star of this star is lonely. If you have an official or a seal, you will be the honorable person of Hanyuan. If the Huagai star is in the sky, you should be a monk. According to the Tao, if a woman lives to violate the Huagai, she will follow the Tao of the monks.
Generally speaking, Huagai is not a lucky star, but it cannot be generalized.
