1/2 of what I currently get per month.

Yes. I wouldn't be able to save though. Car repairs would be difficult to make. I might have to consider a move closer to where I work.

1/4 of what I currently get per month.

Yes. If I lived on my own, the car would have to go, and internet service would be iffy. If I had a roommate, I could probably keep the car. Either way, I would definitely have to live closer to work. I wouldn't be eating out at all.

1/8 of what I take home.

I'm not sure I could do this even with a roommate. I would probably need public assistance. The main issue would be the cost of housing, but food would be difficult too.

1/8 of what I take home is slightly less than what the average Chinese citizen has to live on. Not the poor. The average.
