How many of Disney's six princesses are real princesses?

In China, a princess is the daughter of a king or emperor.

Starting from this concept:

1, Snow White-the king's daughter, a real princess.

Ariel, the daughter of Neptune, is a real princess.

3. Arrow, the daughter of the king, a real princess.

4. Molly-the daughter of the Islamic king, a real princess.

Sandy, the daughter of a wealthy businessman, is not a real princess.

6. Bell, the daughter of a French baker, is not a real princess.

But in western vocabulary, princess and princess are the same word (princess), and they are female royal family members. Therefore, anyone who can marry a prince can be regarded as a "princess".
