Sorry for the inconvenience, but we would like to let you know that we will have a three-days vacation to celebrate The Dragon Boat Festival from 9th June to 11 June. So that there might be a late reply to your question. Thanks for your time and patience.
About The Dragon Boat Festival:
We hold the festival t commemorates the death of the poet and minister Qu Yuan (c. 340–278 BC) of the ancient state of Chu during the Warring States period of the Zhou Dynasty
For thousands of years, who admired him, raced out in their boats to save him or at least retrieve his body. This is said to have been the origin of dragon boat races. When his body could not be found, they dropped balls of sticky rice into the river so that the fish would eat them instead of Qu Yuan's body. This is said to be the origin of zongzi.
Now, Duanwu has been marked by eating Zongzi and racing dragon boat, and i have attached a picture of Zongzi.
