I have been working for 3 years in China. I drew my attention to the fact of the big popularity of dating apps. I asked people about these applications and how it work.
Getting to know and choosing a person in common in China (and not only) apps for single people is very similar to choosing a food in food-app. Basic information for the profile – date of birth, growth and the amount of your earnings per month/year. Nothing about your interests, favorite books/movies/music or life priorities.
Very similar to the pragmatic choice of food on the food capacity. You choose a pizza with cucumbers and mushrooms, because you love vegetables and, of course, mushrooms.
Or you don’t order salad with salmon because you can’t stand the fish. You choose a person the way you choose food.
