What is the significance of the inappropriate slogan "Grow up and marry Dad" in Shenzhen Metro?

I think the original meaning of this slogan is to marry a man who is kind to himself like dad when he grows up, but this sentence is not good enough, and it is a bit strange. It is a bit ambiguous to marry dad when he grows up. This slogan was put forward by New Oriental Shenzhen School. At the beginning, the main idea of this slogan was that children's words were unscrupulous.

I think I might want to promote my school and recruit more students. However, the wording of this advertisement is quite inappropriate, because if we just look at the superficial meaning, it is ethically impossible to marry my father and mother when I grow up. In fact, what the advertising language may want to express is that children think that their parents are very kind to them and want to find someone who is as kind to them as their parents when they grow up. Maybe children don't quite understand the ethical relationship and say this sentence, but from the educational point of view of a child now, children now actually have certain ideas at a very young age. They know the ethical relationship and are unlikely to say such words.

Because the current family or school education still attaches great importance to sex education to a certain extent, it is rare for children to say such things at present. Often, parents and teachers will guide children when they don't consciously say such things, so that they can understand their relationship with their parents and their future relationship with the other half. The Shenzhen Metro has not done a good job of strictly controlling the placement of relevant advertising slogans. In fact, this slogan can be seen at a glance by ordinary people, and it will be inappropriate.

specifically, I don't know why Shenzhen Metro can make such inappropriate advertisements appear on the subway, but it is obviously their own dereliction of duty. The concept conveyed by this advertising language is wrong, and it is not worth promoting this kind of childlike innocence. To a certain extent, New Oriental Shenzhen School has achieved its own propaganda purpose. After all, its popularity has gone up, but this popularity has been scolded, and people will doubt the teaching philosophy of this school, because this slogan is really not in line with the ethics.
