#外孙子应不应该带#既应该带, it should not be brought either.
Should bring: When the grandparents of the grandson are not alive and there is no one to bring, the grandparents should bring.
Don't bring it: When your grandparents are alive, your grandparents shouldn't bring them.
After all, there is a difference between "inside" and "outside", and the word "outside" makes the identity of the grandson clear, and the grandson is an "outsider" after all, and he cannot pass on the ancestry and inherit the future. To put it bluntly, it's okay to bring your grandson, you let your grandson try it with your grandfather's surname, but I'm afraid that most people won't agree.
Personal opinion, please criticize if it is not right.
