I think as you are a very busy man , it will be difficult for you to learn the language which is so different from Chinese , don't you think about engage a translator? I don't think it's difficult to find a Chinese who knows Russian.

Dear, thank you for you response. Actually, I'm just an employee of our company. I don't think my boss would engage a translator for me. Anyway, thanks for your suggestion.

I entirely agree with what Irina just said. It takes much time to learn the basic rules of Russian grammar. You've got to approach this language more seriously. But of course, if you need to find out how to say something in Russian, you only have to ask.
