Hi, we've just moved here ED for a month, and we are a chinese-french family, my 5 years old son speaks fluently french and a little mandarin. When we were in France, we had a lot of chinese (or half) friends in my village, children even adults can exchange chinese culture, and practice mandrin together. Don't hesitate to add my wechat "petit-nicolas" if you know or you are looking for also. Thanks
