What was the end of sister-in-law's Three Kingdoms period? Why don't I understand?

You see, I am so wronged. This is unfair. Big boss, weak second, shameless third, plus a sick old lady. Really speechless. The ending should be to look at the unprofitable marriage and cheat money to leave. After the second child was cheated, his career went bankrupt and he was seriously ill. Feng Xue came to visit because he had no intention of hearing about it. He stayed at the request of the whole family and He Ping, and soon gave birth to a son. The third son was ill. In order to save the child, he sought medical advice everywhere. The boss selflessly saved the child. The third child began to struggle well. The third daughter-in-law regretted what she had done before, and felt guilty and grateful for her eldest brother and sister-in-law. The relationship between the brother and sister has eased, and she is no longer idle. Eldest brother and sister-in-law successfully got the house payment for demolition, bought a house and lived a world of two people. The old lady likes the third child so much, let her serve the third couple. And the second son, let's serve together.
