In the reed leaves,
Wrapped are sticky rice, purple beans and red dates;
At beginning of the fifth lunar month,
The Dragon boat Festival wafts Lisao poetic melodies.

白米红枣紫沙粽
包进千年追思情
芦苇翻浪离骚曲
糯叶流香五月风

In the rice, red dates and purple beans,
the millennium memory is wrapped
Accompanied with Li-Sao reeds wave
In May wind wafts the scent of reed leaves
