      At the age of nineteen, Xiliu married Gao Sheng, who had just lost his wife and had a son named Changfu. A year later Xiliu gave birth to a boy Changhu. Before long, Gao Sheng died of illness.

Seeing Changfu didn't often go to school, Xiliu sent him to work with the poor boys as punishment. Changfu could not stand and wanted to return to school. Xiliu refused, and Changfu, like a beggar (乞丐)， huddled(蜷缩) himself up with cold. Xiliu said to Changfu, "If you are ready to take a beating of 100 strokes, I'll take you back." Changfu decided that he would take the beating. Aware of Changfu's regrets for his mistakes, Xiliu did not beat him and asked him to continue his studies.

      Changhu was a slow-minded child, so Xiliu asked him to quit school and work in the fields.

      But Changhu was so lazy that he often ran away from work. Xiliu then asked him to do business, but he used up all his money in gambling(赌博)． At last, Xiliu sent him to Luoyang to sell goods, where he was put into prison for using fake (假的) silver. In prison he suffered a lot. Xiliu told Changfu, "I gave the fake silver to your brother on purpose, intending to make him suffer. Now you go and get him out." Back home, Changhu knelt before his mother and finally gave up bad and returned to good.
