Many years ago, there was a king in China. He was a brave man who did lots of belifits to the people. He admired a beautiful girl and made her stay in the palace so that he could see her whenever he wanted. But, the girl did not like the frightful figure of the king. She seldomly spoke a word in the palace. Every time the king went to her place, he used to show her some treasures and brought some gifts to the girl in order to make her smile and speak.

On every full moon, the girl would burned incenses and wax candles to worship the moon. People believed that there was a god lived in the moon that made the moon shine. Girls who wanted to be a beauty and have a handsome husband should worship the moon.

One day, the full moon of the eighth month, the king brought three herbs pills to show her.

"This is from the priest of the palace. If I eat them up, I can live forever." He exclaimed.

He continued, "If you and I both take one, we will both live forever. No one can take you away from me!"

Because the king afraid of the pills would have side effects. He forced the girl to take the pill first. If nothing wrong with her after taking the pill, he would take it immediately. However, the girl recognized that if she took all three of them, the king would leave her eventually. Therefore, for the first time, she spoke to the king, "Let me have a look of the pills first. Otherwise, I will not try at all."
