I really don't understand the practical significance of doing this ranking. For the definition of happiness is different from person to person, and it is the same between cities, it is difficult to have a unified standard. There is a cross-talk that says well, for happiness, maybe someone eats a meal of mountain treasures and seafood and feels very happy, maybe someone feels happy because of constipation and pain, do you say that this is comparable!
