《Sad mother and child》Ep13:Episode 13
Wu YongNan suspected that her mother poisoned her father by using a spicy soup made of nitrite for her father. He decided to test her mother. He first showed the mother the article he wrote "Beware of Food Murderer". Han SuMei said he was illiterate, but she said she knew long ago that such a thing was poisonous, So I have not used it. However, Wu YongNan clearly remembered a bag of nitrite in his home when he was a child. Wu YongNan again mentioned that he had to drink the spicy soup made by his mother to his father, and Han SuMei did not react abnormally and was happy to go to Wu YongNan. Li MinNa is very worried about Wu YongNan. She is afraid that Wu YongNan will make a living and persuade him not to worry about it again. Wu YongNan, however, has no other cause to make clear.
