15 years, what month is the Hui people unable to get married?

Muslims have no taboos, do not look at the days, and do not draw lots for divination. Ramadan (Ramadan in September) is not suitable for marriage every year, while Ramadan and Sherbanai are forbidden months, so it is not suitable for marriage to prepare for fasting. But I just said it was inappropriate, not impossible. Again, Islam does not look at the sky and has no taboos.
