What is the prediction of ancient geomantic master Li?

There is a folk story about Li Liang's fortune telling. A middle-aged man asked him to calculate his wife's pregnancy. Li Rang he wrote a word, the man excitedly wrote a crooked word "dragon". Li said that his wife may have dystocia, but judging from the man's face, he is kind-hearted and has accumulated virtue from his ancestors, so although his wife Sue has dystocia, she is not worried about her life. However, because this person's handwriting is written with an extra dot, it looks more like the word "deaf", so Li calculated that his child would be deaf at birth.

Later, the man asked Li about the sex of the child and the time when his wife gave birth. When Li Suan comes out, give him the child and give him an answer five days later. Five days later, his wife gave birth to a baby boy, who was born deaf. Although the delivery was not smooth, the mother and son were safe, and everything was exactly the same as Li's calculation.
