If you really were able to control your living expenses to less than $5 a day, you'd be sick with malnutrition for sure.

Where can you get enough to eat for 5$ a day these days.

You just eat veggies, it's not enough, nowadays green vegetables are a few dollars a catty, and the price has gone up a lot.

And you're still living in a high-income, high-consumption city like Shanghai, Guangzhou and Shenzhen.
