In Miss Mermaid, why do Rui Ying and Ma Jun's parents object to their marriage?

Objection is because both mothers hate each other, and consent is because there is no way.

Ma Jun's mother used to have a good relationship with Yaliying's mother and Ruiying's mother. Ma Jun's mother, Zhao Yingchun, came from a poor family. The whole family rented in Yaliying's mother's house and was taken care of by Yaliying's mother Jinghui. Ruiying's mother, Shen Xiu, is very arrogant and selfish. Because of her good family, she always bullies Zhao Yingchun. So the relationship between three people was established at a young age.

In Korea, children whose parents are divorced or remarried will be discriminated against when they get married. Zhao appreciated Jing Hui's help and saw the excellence of Yaliying, so he wanted to fix Yaliying and his son. Zhao hates Shen's oppression from childhood and doesn't like his son marrying a girl who has lived like a princess since childhood, so he strongly opposes their marriage. Shen Xiuzhen objected more because she didn't have Ma Likun. She thought Ma Jun was a wimp and relied too much on her mother. Zhao Yingchun exposed the shortcomings of his family, separated Ruiying and Wang Zhu, hurt Ruiying and became more hostile to himself. If Ruiying is her daughter-in-law, she may be abused, and Ruiying has a better goal.

However, Rima Yaojun insisted very much and even lied that they had spent a good night together at the ski resort. Parents of both sides can only accept this situation helplessly.

Really answered a sentence that often appears in TV series: Which parent can forget their children?
