In fact, it mainly depends on whether you like doing this, whether you do it for a long time, and whether you have a future (for example, big companies can train new people and get promoted). This job is relatively easy, that is, taking a questionnaire to find someone to do in a crowded place. It's best to go to a leisure place, because people in these places have nothing to do and may give you a questionnaire. I watched a TV in which the man went to the hospital lounge for investigation.
