Few people think of marriage as a child's play and divorce every time. If marriage is like trial and error (if it turns out that there are no wrong choices in marriage, both parties will be happy and old age), and divorce is like "correction". On the one hand, the law is "Trial and error" provides convenience, and it should also provide convenience for "error correction". It can even be said that providing the latter convenience is more important than providing the former convenience. This passage mainly says? ['Marriage is a process of trial and error.', 'Some people have a casual attitude towards marriage and divorce.', 'Marriage is for trial and error.', 'Freedom to divorce must be guaranteed.']
