Which is more prosperous, Hanoi or Saigon (Ho Chi Minh City)?

Ho Chi Minh City and Vietnam are a bit like us, not only in political system, but also in urban style. Like Shanghai, Ho Chi Minh City is the largest port and aviation hub, the largest city, the largest industrial base, the largest population, the deepest degree of internationalization, the largest built-up area, the largest economic aggregate and the most prosperous city in China, and was even once called "Paris of the East". Hanoi, like Beijing, is the capital of China, the second largest city in China, a political center and a famous historical and cultural city with a large total area.
