Summer is hot and humid. Smell the peanuts on the pig's trotters. Are some bugs flying around the peanuts on the pig's feet? Touch the peanuts on the pig's feet to see if they feel sticky. If the above feeling occurs, it means that the peanuts on the pig's feet are broken and can't be eaten.
It is suggested that overnight pig's trotters and peanuts be kept in the refrigerator for consumption.
