Did Sun Shaoan die in the TV series Ordinary World?

I remember Sun Shaoan as if he were dead. He and Xiulian went to attend the inauguration ceremony of the primary school. He asked Xiulian to go first. As a result, Xiulian just sat there and fell down at home. Moreover, when he was dating Xiulian, he also said that the fortune teller said that he was short-lived. Why are TV plays different?
