Let's take a look at the key characters in "Parents Love" in which An Jie and Dehua have a better relationship, and she plays an indispensable role in it!
She is Wang Zhenbiao's first wife Zhang Guiying! In fact, compared to An Jie's best friend Ge Meixia, I prefer to believe that Zhang Guiying is An Jie and Dehua's best friend! Zhang Guiying is actually a tragic character in the play, she has done all the dirty work in her life, but she does not have the blessing to enjoy a happy life. 
She is kind, warm, cheerful, kind, and although she has no culture, she knows how to respect others. When An Jie was pregnant with twins at that time, everyone called her "Double Stick", even Teacher Ge, who was as educated as An Jie at that time, called An Jie "Double Stick". But after Zhang Guiying heard that An Jie's son Jiang Weiguo came to report the good news that An Jie had given birth to younger brothers and sisters, she blurted out: "Really, I gave birth to twins, come in, my aunt will bring you food." ”
She is the only one on the island who doesn't say that Anjie is a "double stick"! When she saw An Jie being ridiculed by the children for carrying water, she also rushed over to drive away the children as soon as possible, even if it was her own child Wang Haiyang, she also cleaned up. Then silently helped An Jie fill a tank of water, and when An Jie first arrived on the island, he also arranged for his son Wang Haiyang to come over and send dumplings to An Jie. 
Zhang Guiying is actually a women's director and has some careers of her own, because she followed her husband Wang Zhenbiao to Songshan Island and became a housewife. I did the messiest and heaviest work in the house, but Wang Zhenbiao disliked her in addition to disliking her! She and Dehua went to catch the sea, accidentally fell into the sea, almost drowned, and met Wang Zhenbiao and Jiang Defu when they came back halfway. 
Dehua said: My sister-in-law fell into the sea and almost drowned. After saying that, the two of them couldn't laugh. thought that Wang Zhenbiao would feel sorry for Zhang Guiying when he heard it, but after Wang Zhenbiao heard it, his eyes were full of disgust, and he didn't care about whether Zhang Guiying would catch a cold or not.

There was only a cold "hum", Jiang Defu said that An Jie had no strength, and he couldn't even pick up the water, and he saw Zhang Guiying carrying the water and walking steadily. Let's just say that Zhang Guiying is really capable and has a lot of strength, but Wang Zhenbiao thinks that women should work so hard, full of belittling and contempt! And in the end, Zhang Guiying got sick and died, after working hard all her life, her life became better, but she left, she is really a tragic character! 
So why is she the key person in the relationship between An Jie and Dehua to get better? Because Zhang Guiying is not a person who makes irresponsible remarks behind her back, she also said earlier that she is kind, cheerful, and knows how to respect others. So every time Dehua complains about her sister-in-law An Jie with her, Zhang Guiying will not stand in Dehua's perspective like Wang Xiu'e and complain about An Jie with her. 
Instead, he will help Dehua ease her emotions, and then give Dehua suitable advice. For example, Dehua asked her sister-in-law if she would burn paper for her parents to commemorate it, and An Jie said that she did not have this habit. But after being scared by Dehua for a few words, An Jie ran outside to burn the newspaper alone at night. 
As a result, Dehua knew about this matter, and then ran to complain about An Jie with Zhang Guiying, but Zhang Guiying told Dehua that the two of them could go to help An Jie burn a piece of paper at night. If Wang Xiu'e knew about this matter, then she and Dehua would definitely say that An Jie was not, but Zhang Guiying didn't, she was trying to find a way to help An Jie and Dehua. 
It is also because of this paper-burning incident that the relationship between An Jie and Dehua has eased a step and become much more intimate. Both people start to make changes, change for each other's sake, start to slowly get used to each other's habits, and two people influence each other. 
That's why there is the best model of sister-in-law relationship now! It can be said that Zhang Guiying played a mediating role between An Jie and Dehua, and was also the key person in their relationship to ease and improve!
