"Ziling, what illness has Grandpa contracted?" Yang Qingyin asked Luo Ziling anxiously.
Yang Yuanshan had always been in good health, but he enjoyed smoking and had been a smoker for at least fifty years.
He had developed the habit of smoking while serving in the army. After demobilization, he had quit temporarily, but started again due to troubling circumstances, using it as a way to soothe his worries, and the addiction stayed with him for life.
Many people had advised him against it, but he didn't take them seriously. Smoking had become an indispensable part of his life.
When others advised him, he would compare himself to Zhang Xueliang and Hero Mao, saying that they didn't care much about such things, and both of them lived long lives.
Yang Yuanshan was very stubborn; if he didn't intend to change his mind, no amount of persuasion from others would help.
