Hello, Helenlin. Greetings from Glasgow, and welcome to Scotland.com.
I like the idea of a brother who cooks for you. Perhaps you could send him here to cook for me.
I think you said you are in China? Wonderful! You have very good English. (Glasgow, where I live, is "twinned" with Dalian in China, but I don't know anything about China, really. Sorry. Again, welcome.
