'China' did a good job?

Please, there's more than hospital in that country, you know? Which is quite likely to be a private business too. Maybe you should give respect specifically to where it is due, such as the individual hospital, unit, team or staff member rather than diluting it with a generic thank you note that you seem to intend to deliver to all 1.4 billion citizens.

Happening to have a singular good experience in China does not warrant praising the whole damn country. If you are going to look at regional industries as a whole, many a medical doctor (that you may end up tutoring when he finishes work) will be able to tell you that not all is good when it comes to healthcare in China, mainly due to corruption and bizarrely in what is supposed to be a Communist country, a hyper-capitalist mentality exists; often leading to false diagnosis, kickbacks etc.

Jesus... If I praised China every single time I received good service or enjoyed a pleasant experience there, I'd soon be able to steal DaShan's job as the defacto laowai ambassador.

Likewise, we do not declare that China is a shit place to work because of one single shitty school. However, when there are hundreds of shitty schools, then we may choose to look at the trends which are occuring as a whole. But, ultimately, it will always be the offending individual business whose reputation will take a hit.
