Hi there, I have a question about "have been ... since ...". The complete sentence is "There's not been a king since the first court." I wondered that is there a king in the first court? Is the state of "no king" started from the first court or the end of the first court? Furthermore, if the sentence changed to "There's a king since the first court." Is the situation similar? Thanks!

Main differences between "triditional Chinese" and "communist Chinese" (Part 2) Please review it, thanks! It would not be blamed that people pursue fortune and social status, or beauty and glory; it is natural, but the moral criterion has changed as the misunderstanding of some philosophic and scientific theories. The most sophistical one is saying that stronger people win the game no matter the method they use and it is justified by so-called "social Darwinism", i.e. survival of the fittest. This sophistry sounds scientific but is a pseudoscience. Its advantage is simply from breaking rules but not strength. No one can get that kind of advantage in a wild world since everyone is allowed to do anything in that environment. Therefore the "social Darwinism" is a pseudoscience claimed by sociopaths but should not be socialists.

Essay exercise: Main differences between "triditional Chinese" and "communist Chinese" (Part 1) Please review it, thanks! The main subject of this essay is not about politics, but this political correctness is the most apparent change that communist politics have made to current Chinese society. I noticed that by comparing those societies that also affected by ancient China, such as Japan or even Taiwan. People in nowadays China value fortune and social status more than anything else, they call this "the nature of wolf", that is, to take what you want by any ways you can, and that doesn't mean that you have bad table manners but shows your ability, your power and your charisma. However, we have to admit that such wolf totem originally comes from those nomad tribes who have been enemies of Chinese agricultural ancestors for thousands of years.

Two questions about a little bit difficult sentense. "This company has a special deal for clients where they offer a discount of 20 percent if you return for a further class." This is a sentence from Cambridge IELTS13. I don't understand the two places. 1. "where". ("... clients where they ...") What's this "where" pointed? 2. "further". (" ... return for a further class.") Does "further class" mean the next class or the last class? Google translate gave me a translation of the last class but I don't understand why. Doesn't further mean "the next"? Thanks!
