你说的挺对的，而且如果有一个人姓氏不好听，也可以跟着另一方姓呀。日本还有夫妇同姓，意思是结婚了女性加入男性的家庭，男性把自己宝贵的姓氏给予女性。有感情就行了，也没必要这么在意形式
You're right, and if one of you has a bad last name, you can follow the other one. There are couples in Japan who have the same last name, meaning that married women join the male family, and men give their valuable last name to the female.
