Which sounds better, princess or princess?

I think which one is better, princess or princess, depends on what the previous title is. The title is good, and the title is naturally good. No matter how many people call, as long as the words in front are added, they can be different.

In the Qing Dynasty, Princess Jou-chia sounded better than Princess Shun. Princess Duanjing is better than Princess Dunke. Honest princess is better than Zhenshou princess.

so, princesses, princesses and even gege are all good, depending on how you use them.

personally, if you don't count the previous name, it's better to listen to the princess. As you said, there are too many princesses now, which are tacky.
