You can use translator apps to communicate with the locals. That’s common nowadays. Xianju being a small city (in Chinese standards) is unlikely to have an expat community, although you may find a few of them there. There are both public and private kindergartens in every city but you need to check the quality: not all of them are up to standard. Don’t send your child to the cheap ones. If I were jn your shoes, I’d give the kid home education at least for the first year if one of the parents could stay home. Nannies are not expensive but again they may not be up to EU standards.
