What episode is the death of Amy's mother and my three sisters?

10 episode. Han Mu died of a heart attack.

Han's mother wanted to solve the conflict between the two sisters, but because of unfairness, Han Aimei became more and more angry and immediately turned away. Other sisters and brothers saw it and quickly stopped her. In the end, Han Aimei said that Xu Baolai would be the factory director, otherwise the mother-daughter relationship would be cut off. It is precisely because of Han's mother's biased treatment of her children that the deep resentment of her eldest sister, Han Aimei, finally broke out after years of repression. Under the pressure of Han Aimei, Han's mother had a heart attack and fell into a coma. She never got up again until Han Aisong and Han Aizhu suddenly woke up holding their mother's portrait. All this is so unexpected.
