Dear Xiaohua,
It is four days since Mother accepted the operation. She is feeling much more better. The doctors told me the operation was successful, but because her old age she had to stay in hospital for other two weeks. The doctors also say it was quite necessary for her to do so. We expect to get a full report in two and three days. Please tell the good news to rest of the family as fast as possible. You needn’t come here. I’m able to look after Mother by himself. You’d better send flowers to Mother. She will feel happily.
