I hate to disagree with you Ran but that is completely incorrect, the Chinese vernaculars did not start shifting at that time. You can do more research by looking up Middle Chinese and Classical Chinese. The Mandarin never altered the King sound to Jing sound as quickly as that. Most of the colonial invasion came from the Southern Coasts in those days, thus, they romanised from Cantonese and Minnan. Kirin is romanised according to the dialect around Jilin at a different stage that is why it is not calle Katlam. By the way, you are really offensive by blocking me yesterday. You did not read the regulations on Wikipedia that you are not supposed to call users who are newbies Vandals. That is an abuse of your privilege. I notice a lot of experienced editors here who like to block and delete the text contributions of newbies are really mean. Why are educated people so mean? This is a free world and we all have a privilege to speak out part but should also listen to others and not be so quick to censor others.
