"Grandfather Yuwen's complexion is normal, but his lips are a little blue. If I'm not wrong, Grandfather Yuwen's old illness has been acting up recently, and he has only recently gotten better. However, as he gets older, this cardiovascular problem is a little serious. Therefore, Grandfather Yuwen's mood doesn't fluctuate too much, not to mention those violent movements. Therefore, Grandpa should now know why I wanted to stop you," Chen Meng'er explained to Elder Liu.
