Is that true?

There is this girl I talk too who is Chinese(born and raised there been in the US for few years). It seemed at first she may have liked me. Said I was cute couple of times. A little after we met, she asked if I had a girlfriend and all. When I said no, she said why. Anyways, recently she called me brother. At first I thought, oh she probably sees me as a friend. Which is fine. However, I saw online that in China, sometimes girls call guys they like brother though. Is that really true? Everything between us has been friendly. And when she said it it was when we were just casually chatting. It's not like I asked her out and she said that. I was just curious what brother means exactly from a Chinese girl.
