European Union citizen going back from China

Hello, I am an european studying in Beijing for the time being. In February I will have to go back to Europe.However, I would like to get some fake watches with me in Europe. Therefore, how many can I get with me without having to pay tax? (I am a watch fan, and would like to get as many as possible with or without boxes). Moreover, friends ask me if I could bring them some gifts...like watches. So can I get at least 10 watches or more? Thank you!
