    Dragon-Boat Festival is also called the Duanwu Fes-tival. It is celebrated on the fifth day of the fifth

monthaccording to the Chinese calendar. People hold the drag-on-boat races to remember Qu Yuan,

one of the greatestpoets in China. Now we read his poem Li Sao which wasfilled with deep love for his

country.    

    Qu Yuan was borm in Zigui of Hubei Province over2,200 years ago. Qu Yuan was an honest ministry

of theState Chu, during the Warring States period ( 475-22IBC). He tried to make the country stronger,

but hefailed because some bad officials were against him strongly. At last, he was very disappointed. He

ended his life by throwing himself into the Mi Luo River. It was said that people jumped down from boats

to try to save him at that time. But it was too late. In order to keep the hungry fish away from his body,

people threw rice into the river.    

    We can watch the dragon-Boat race and eat a kind of Chinese food named Zongzi during the Dragon

boat Festival.
