So your national dish is Chinese?
Not traditional Chinese, no. The accepted history is that, while working on the railroads back in the 1800s, Chinese cooks came up with the dish as an easy facsimile of cottage pie or shepherd's pie that could be made with ingredients commonly available (ground beef, creamed corn, and potatoes - the creamed corn meant they didn't need to cook up a separate gravy). Canadian railroad workers took the dish back home.
