China's / Chinese What's the difference between China's and Chinese? Thank you so much.

Dog Bark The neighbours on the fourth floor have a white dog, they call it Little White. Sometimes when I return home, the owner is walking the dog, and it often barks to me. Every time the owner says to it:"why do you bark again, he is my neighbour, don't you know him?" I feel it is pretty weird, some people think that a dog barks means it is not friendly to you. However, a dog cannot speak human languages, it can only bark to express its emotion. Maybe Little White just wants to say "hello" to me. Please give me some suggestions about words and grammar. Thank you so much.

Chinese teachers are in the U.K. I have watched the final episode of Are Our Kids Tough Enough from BBC today. After 4 weeks, the students taught by Chinese teachers had an examination with their counterparts taught with British teaching style. The result was that Chinese teachers' students' scores were higher than others in each aspect (science, mathematics, Chinese Mandarin) In my look, the competition is a little bit unfair, because the time that students in Chinese style spend is double than others. In the end, I think every education system has plus points and drawbacks, I mean no teaching method is the best in the world. Please give me some suggestions about words and grammar, thank you so much.

Chinese teachers are in the U.K. I watched a documentary named Are Our Kids Tough Enough (CHINESE SCHOOL) form BBC yesterday. I noticed that one of these Chinese teachers thought British high social welfare is the reason that some students do not study hard, because they do not worry about their lives after graduation. However, the headteacher did not think so, he believed there must be some other reasons. Please give me some suggestions about words and grammar, thank you so much.
