China - changes in 20 years

My first visit to China was in 1987. I recall my impressions of that visit:

* foreigners are required to use the "foreign exchange certificate", which has a higher exchange rate compared to the local currency.
* tourists pay a higher admission ticket to the tourist spots, compared to locals
* the toilets were unclean
* there are many people to provide service

I am now in China again, nearly 20 years later. I saw the big changes to the lifestyle and the standard of living.

* the cities are now similar to other cities around the world
* there is only one currency
* prices are now the same for locals and tourists
* there is inadequate workers to provide service

Somehow, I miss the old China.
