The living standard in our country is so poor that the average salary of ordinary people is only 4000~6000.

Eating KFC is too extravagant.

Americans and Japanese eat hamburgers, because American hamburgers cost 1 USD each, and the average monthly income is 6000 ~ 8000 USD.

In other words, people earn $25 an hour.

You can eat 25 hamburgers an hour.

Our Hamburg in China is RMB 15, which is equivalent to more than US$ 2.5. Our per capita income in China is RMB 4,000-6,000, which is equivalent to US$ 615-923.

In other words, the hourly wage of China people is 15 RMB, which is equivalent to $2.

I can't afford a hamburger for an hour.

So it's up to you.
