Why do so many people die between Tomb-Sweeping Day and the 15th day of the seventh lunar month?

There is a folk saying that "Qingming Festival is on March 3rd, and beginning of autumn is on July 7th". In Tomb-Sweeping Day, there were many people burning paper, and the fire hazard was one of them. Secondly, in China, the festive atmosphere is strong, and many elderly people have the custom of offering sacrifices to their ancestors. In China, there is a unique saying that graves are safe and blessed with feng shui, which leads many middle-aged and elderly people to burn paper on their graves regardless of their physical condition. The so-called feng shui treasure land is mostly in the forest surrounded by mountains and rivers, and the roads are rugged and changeable, which is easy to cause slipping; Third, Yin Qi was too heavy in this period, which is the theory of ghosts and gods. The fifteenth day of the seventh lunar month is called the Mid-Yuan Festival, also known as the Ghost Festival. According to legend, ghosts like to come out to beg on this day. People with yin and yang eyes can see it and are easy to be touched, such as "ghosts hitting the wall". To put it bluntly, many people are scared to death because of psychological effects!
