Second, Jacky never makes trouble. Jacky can get the love of Xiang Huaqiang and his wife. A large part of the reason is that he never caused trouble to his parents since he was a child. This makes Jacky's parents have to love Jacky more. After all, most parents don't want their children to be too naughty, and they don't want their children to cause themselves too much trouble. This is where Jackie always does better than You Xiang.
Third, You Xiang was sentenced for beating the driver. As the eldest son of Xiang Huaqiang, You Xiang never did anything to save face for Xiang Huaqiang, but always brought some unnecessary troubles to Mr. and Mrs. Xiang Huaqiang. Many times, in the name of his father, Xiang Huaqiang, You Xiang will do something that will disgrace his father's reputation. This is also an important reason why Xiang Huaqiang and his wife ignored You Xiang. Most importantly, You Xiang was sentenced for beating the driver. Mr. and Mrs. Xiang Huaqiang have been chilling about their eldest son's behavior for a long time, so they ignored You Xiang.
To sum up, the reason why Xiang Huaqiang and his wife are so different from their two sons is mainly because of their different personalities. The eldest son always makes trouble for himself, and the youngest son is always proud of himself.
