They said that you will become healthier to drink the spring water from the well on the Dragon Boat Day during Horse hour (11.00 AM to 13.00 PM). The story is from late Ming dynasty. A general brought his troop to the hill and couldn't find the water for days. He prayed to the heaven, then struck his sword into the ground and the water spurted out on the 5th day of 5th lunar month at noon.

Once Chinese drank Strong Yellow Wine to clean up the gem in the body on the Dragon Boat Day. The Strong Yellow Wine is made of rice. It's a tonic wine and not good for children. Therefore adult just wipe the children forehead with the Strong Yellow Wine. They believe that will make children healthier and won't catch the 5th lunar month disease.
