As far as the actual situation is concerned, both cities are western cities, each with its own strengths. However, in terms of comprehensive strength, Xi' an is slightly better. After all, as an ancient capital with many dynasties, it has a strong family background and many opportunities for development. Although Guiyang's comprehensive strength is not as good as Xi 'an's, emerging industries are developing rapidly, and there are also many opportunities, especially some specific industries. So which city to choose, it is best to make a decision according to personal situation and city positioning.
