These day you must seen a lot of duck along the road every where in Hue as well as Vietnam. And at any places selling duck is always full of people during these days. Its about the Tết Đoan Ngọ which is the traditional holiday in Vietnam, China and South Korea. The festival occurring on the 5th of May by Lunar calendar. Its about the weather changing period, so people believe today at noon the Yang (possitive element) is most powerful. Therefore, noon is the best time for best of luck. Then people make an offer to worship at noon. In Vietnam Tết Đoan Ngọ is kind of “harvest festival” to kill all the insects bad for the crop. Because this time also is a good weather for everything not except insects growing.
But why these days people eat duck is something seems funny ?
Duck in Yinyang theory is belong to “cold part” and during these days the weather is very hot. There for using duck meat to cooling down will be better for your health. And also duck meat in Oriental medical theory is use as a supplement nutrition for weak or sick people, power your energy. That why people eat duck meat during Tết Đoan Ngọ.
