I'll also provide some common prices in China:
1. Bowl of noodles- 1 yuan
2. Pound of meat- 5 yuan
3. TV- 300 yuan
4. Rent- 600 yuan/month
5. Car- 100,000 yuan
6. Home- 400,000 yuan in city, very little in rural areas.
I'll give some more numbers - still very rough, but better than yours. All figures are in yuan.
Coastal rich city:
1. Average dinner out: 30-100 per person
2. Typical cost for home-made dinner: 10-20 per person
3. Plasma TV: 5000-10000
4. Rent: 2000-4000 yuan/month for a double room
6. Home: 1-4 million for a three beds flat
7. Monthly income for average factory/office worker: 3000-8000
Inland medium sized city:
1. Average dinner out: 10-30 per person
2. Typical cost for home-made dinner: ~10 per person
3. LCD TV: 3000-7000
4. Rent: 300-500 yuan/month for a double room
6. Home: 200-400k for a three beds flat
7. Monthly income for average factory/office worker: 2000-5000
Poor inland rural village:
1. Average dinner out: 5-10 per person
2. Typical cost for home-made dinner: ~5 per person
3. CRT TV: 500-2000
4. Rent & Home: I don't know, but quite cheap.
7. Monthly income for average factory/office worker: 500-2000, could be as low as 200 in remote parts but quite rare.
As you can see the living standard is hugely different from place to place. Comparing with the UK or the US, where cost of living in a big city may be just 1-2 times over that of countryside, in China the ratio is closer to 10. This is not what normally happens in a free market as capital naturally flows into cheaper area. The reason for the huge inequality comes from many governmental policies, notably restriction of movement, tax exemptions in coastal cities, weak public health care and education in the countryside, and in general harder upward mobility.
It may be tempting to think China is "regulation free", in truth it is not. To open a business in China you also have to go through myriad hoops - except they are the wrong ones. Whereas an American regulator demands you to spend on ensuring the safety of your product, a Chinese tax collector "recommends" you to purchase a "specially made" PC, five times the market value, just to file your monthly tax return online. These more tricky parts are, unfortunately, not something you can deduce from tax rates.
