Can Tomb-Sweeping Day fill the grave in leap year?

Tomb-Sweeping Day's theory of not filling graves in leap months.

According to the local stress, there is no fill in most parts of Northeast China. Filling the grave is actually to fill in the soil washed down from the grave by the rain for a whole year, so that the grave can still maintain its original size, and there is new soil on it, indicating that there will be people in the future, and the incense will continue, instead of increasing the grave year by year. If it increases every year, it will become loess hills after many years.

Different places, different practices, after all, different customs, but leap month year can completely add soil to the graves of the deceased elders. It is better for Tomb-Sweeping Day to add soil to the graves in this year than not to add soil in leap year. China has a saying: Nine leaps in ten years. It means that there are many leap months. Think about it. If so, how many Tomb-Sweeping Day can fill the soil? Besides, Tomb-Sweeping Day comes from solar terms, and the lunar calendar in China has nothing to do with solar terms, but two concepts. In fact, filling the soil or offering sacrifices to ancestors are all manifestations of our mourning for our loved ones. Go home as much as possible. Bye. I really can't go home, and it's okay to die a long way.
