What's the difference between Greater Vancouver and Vancouver?

Vancouver has only two districts, East and West. The area of each district is similar to that of New East City and New West City in Beijing. The scope of these two districts is strictly "Vancouver City". Generally speaking, Vancouver actually refers to the "big temperature zone". In addition to Vancouver, it also includes West Vancouver, North Vancouver, Bennaby, Richmond, NoBoursin Forest and New Westminster ... roughly equivalent to Chaoyang District and Haidian District in Beijing ... The boundary between cities is a street, and each city has its own mayor and city hall. The population of Vancouver refers to the population of areas with higher temperatures. Vancouver's business center is located in the center of Vancouver, belonging to the west of Vancouver (not West Vancouver), similar to Beijing CBD. The main stadium of this year's Winter Olympics is also in the west of Vancouver, and the ski resort is in the neighboring Whistler, which is no longer a big temperature area.
