How to study the influence of tourism on happiness, and from which angles should we start? Are there many scales or questionnaires quoted abroad?

I have to say that the landlord's question is a little too big, and the scale of happiness is easy to say, but if you do the "tourism" section, you have to break it down because there are too many related interference factors. "Tourism" and "happiness" can't be related, so the landlord will do a social investigation study.

Let me mention some disturbing factors that I think:

Tourism frequency, types of tourist sites (landscape, culture? Domestic and foreign? Etc.), the number of accompanying persons and the type of accompanying persons (family relationship? Friends? ), the proportion of family income and tourism expenses.

ah, that's all I thought of for the time being. . . . Of course, it is also possible to investigate the happiness before and after the tour as Bai Wenjun personally said, but it is suggested to follow up and be the same person if you want to do it, because the reliability may be reduced if the group changes.
