Why don't Hakka Tomb-Sweeping Day go to worship the mountain?

There are two reasons: First, Hakka people live in the mountainous area north of Lingnan Ridge. Raoping, Chaoan, Jiexi and Liuhe are all places where Hakka people live, and Zhongshan, as the center of the Pearl River Delta, is a place where Hakka people live. Hakka people live in mountainous areas, and the arable land is extremely limited. In addition, they should pay attention to geomantic omen, so they all buried their ancestors on various hills, far from home. Tomb-Sweeping Day is also a busy season for spring ploughing by Hakkas, and "Spring competes for the sun in summer", so the spring ploughing season must not be delayed by sweeping graves, so Hakkas are not allowed to sweep graves in Tomb-Sweeping Day. Second, Hakkas live in poverty. "From the seventh day to the eighth day, every family is eating porridge"; If the child starts school, the tuition fee cannot be borrowed, and even the hens that lay eggs have to be sold; Qingming spring ploughing needs investment. At this time, there is no money and nothing to sweep the grave. How should we face our ancestors? Therefore, in terms of property, Hakkas are not allowed to sweep graves in Tomb-Sweeping Day.
