1. The true meaning
The marriage certificate is a legally binding document issued by the marriage registration authority that can prove the relationship between husband and wife. The "mzhbjzh" below the marriage certificate represents the meaning of "supervised by the Ministry of Civil Affairs" and is the abbreviation of "supervised by the Ministry of Civil Affairs" in Chinese Pinyin.
2. Derivative meaning
But due to the lack of clear records about this string of letters in the Civil Affairs Bureau, the person who designed the marriage certificate layout has also resigned, so many netizens have translated it into many interesting sentences, such as why do girls need to marry this kind of person, why do girls need to get married this way, why do girls need to rush to change, why should girls be serious, and if they haven't found something good, they should look again, and so on.
