It depends on the country and city one lives in as well. $3000 US dollars barely pays for a month 2 bedroom apartment in Silicon Valley, Northern California. But it is much cheaper in Las Vegas, Nevada. Don't forget medical bill can be very expensive, in particular in US.
Based on yr description , I think 合肥 is cheaper & more FOOD to choose than Laos .合肥 hotel room was RMB 80 .I went from 合肥 to 安慶 to see 長江 ,hotel was same @ RMB 80 ,& 👍FOOD , only 迎江寺 was closed . 合肥 fruits is same price as 珠海 but food cheaper . 🌈🌈
