I haven't done any business like M-Kee or FKC, but I judge that they are definitely not Japanese. On a daily basis, you can find some private shops, such as those that help others sell things (you can consider dishwashers if you are tired and dirty), or KTV. You won't know until you go to those places and ask if there are any jobs. There are many outdoor shops in the commercial street here, and they will ask some odd jobs to help them, and they will get paid every day in 51 yuan.
