Both husband and wife are mainlanders, and the wife's work visa is in Hong Kong. If I go to work in Hong Kong, how long will it take for my husband and wife to get permanent residency in Hong Kong?

If your wife is a gifted student, you can go to Hong Kong to work and live and be a wife!

When you arrive in Hong Kong, you will be a non-permanent resident of Hong Kong within seven years. After you have lived for seven years, you can apply for permanent residency and become a permanent resident!

But within seven years, if your wife doesn't work in Hong Kong (before she gets a Hong Kong permanent identity card), then your endorsement will be suspended, and you must leave Hong Kong with her, so you can't apply!

As for how long it will take to obtain the permanent right of abode in Hong Kong (the right of abode, not the right of abode), your wife will definitely arrive in Hong Kong before you, and she can apply after living in Hong Kong for seven years. You can also apply if you have lived in Hong Kong for 7 years! Always a person who has lived for 7 years! It is impossible to say that your wife lived with you for seven years. At that time, you were only four years old. Your wife obtained permanent residency, and so did you. This is impossible!
