What's she like?

In Chinese:

她的性格怎么样?Tā de xìnɡ ɡé zěn me yànɡ?

Explaination:

1. tā: he/she

2. tā de: his/her

3. xìnɡ ɡé: character

4. zěn me yànɡ: how, how about

Extension:

"zěn me yànɡ" is a very common and useful word when we want to know how is something or someone. The sentence structure is like this: noun + zěn me yànɡ. For example:

1. A friend went to Beijing for 3 days. When she came back, we want to ask how was Beijing. We can say:

How was Beijing?

北京怎么样?

Běi jīnɡ zěn me yànɡ?

Then the answer could be hěn piào liɑnɡ(very beautiful), hěn hǎo(very good) etc.

2. Surely zěn me yànɡ could be used to ask about something, like clothes, food, drinks etc.

How is this skirt?
