Wu Zixu threw 1200 gold into the river. Why did Wu Zixu do this?

Wu Zixu threw his daughter into the river because a woman once brought him food by the river, so he was very grateful. Wu Zixu was a native of Chu at that time, and his father was responsible for teaching the king of Chu. Because the prince was framed at that time, and his father was also implicated. As a result, Wu Zixu was killed, so Wu Zixu and the Prince prepared to flee to Wu. However, due to the long journey, they were tired and hungry all the way. When he arrived at the border of Wu, he was penniless and very hungry.

At this time, they saw a woman washing clothes by a stream, and the woman put a box of food beside her. At this time, Wu Zixu got up the courage to go forward and said to the woman, can you give him the food? He's so hungry. But because of the long journey, Wu Zixu's image is sloppy and poor. After Wu Zixu explained, the woman gave them the food. After eating, Wu Zixu told the woman that he was wanted by Chu, but was framed by others.

After hearing this, the woman felt very sad. After they left, they became more and more sad and finally jumped into the river. Wu Zixu had gone a long way and found something was wrong, so he looked back and found the woman's clothes on the shore, but no one was found. So Wu Zixu wrote a few words on a nearby stone with the blood on his finger, and finally buried the stone under the soil.

Finally, Wu Zixu successfully fled to Wu, which was highly valued by the Emperor of Wu. Not long after, he led troops to attack Chu, dug up the tomb of King Chu Ping, and took out his body and whipped it to avenge his death. When he passed the original place, he dug out the stone, kept his promise and put 200 pieces of gold into the water.
