    Liu Yan: Excuse me, whose coat is this? Is it yours?

    Bai Yang: Let me see. No, it isn't mine. I think it's Ling Ping's.

    Liu Yan: Ling Ping!

    Ling Ping: Yes?
    
    Liu Yan: Is the coat yours?

    Ling Ping: No, it isn't mine. Mine is black, but this is brown. I think it's Xiao Liang's.

    Liu Yan: Xiao Liang! Is this coat yours?

    Xiao Liang: Yes, it is.

    Liu Yan: Here you are. You must look after your things carefully.

    Xiao Liang: Yes, thank you.
