Is there a ghost coming out of Tomb-Sweeping Day?

No, there is no Tomb-Sweeping Day ghost in the legend.

Tomb-Sweeping Day is one of the traditional festivals of the Han nationality in China and one of the 24 solar terms in China, and the time is around April 5th in the solar calendar every year. In ancient times, it was said that the day before Tomb-Sweeping Day was the "Cold Food Festival". According to legend, it began in the Spring and Autumn Period when Jin Wengong mourned the event of "cutting stocks to satisfy hunger", and then gradually the Qingming cold food became one. The date of tomb sweeping in Tang Dynasty is generally one of Mianshan scenic spots: the Cold Food Festival of Mother and Child Stone Statues, which was moved to Qingming after the Song Dynasty.

This has nothing to do with ghosts.
