The Chinses Work Ethics is very INFERIOR. I mean it in every sense of word. These people are not properly trained and DO NOT understand the value of serving others. They do not have the spirit. They are interior humans. They worship money and that is what they do. What you have experienced in 1995 in Chinese Embassy is a shame to all decent Chinese. The trouble is, none of those officials or non-officials feel that way. I tell you (the author) what, what you have experienced is caused not by the old lady herself, but is caused by Mao's legacy. Mao has virtually destroyed the "goodness" of Chinese culture, our compassionate love for human (or each other) has been deterioted and downgraded. We are not brought up with basic human courtesy values. Yes, I can fully understand your situation. When a human's moral character is missing, s/he is basically an ASSHOLE. It is just a fact of life, that MAO's age produces a lot of assholes and the one you encountered in Chinese Embassy is just ONE OF THEM.
Their work ethics sucks.
