Let others fill in the questionnaire online and offline in different ways. The only similarity is that you want others to see the benefits, and others will not help you fill out the questionnaire for no reason. It is best to send a small red envelope to others in the online questionnaire. Now many online links are reluctant to click, because there are too many telecom frauds, and many people are worried that their money will be stolen because they click on an unknown website, so they are more cautious. If you want to find someone else to add a questionnaire online, you'd better find someone younger, because these people don't care so much. He may have just clicked on your website out of curiosity and made a questionnaire for you. Young people are not so defensive. As long as your website is safe, these people will call people around to help you fill out the questionnaire. As long as you fill it out and send them a small red envelope, they will feel very satisfied. It is very popular to grab red envelopes online now. Some red envelopes may cost only a few cents, but everyone is still very excited to grab them. So you can send out red envelopes in many groups, and let everyone fill out a questionnaire for you after grabbing the red envelopes. People are still happy to do this, and the cost is very low. Fill in the questionnaire offline and give small gifts. You are not so prepared for offline investigation, because you just take a piece of paper and let others help you make a few options. If some people have a lot of free time now, they will be willing to help you complete your questionnaire. You can buy some cheap gifts for people who are willing to help you fill out the questionnaire. Some small gifts cost very little, and many people like to take them home for their children to play with. As long as these gifts appear, others will take the initiative to help you fill out the questionnaire. Whether online or offline, these people are helping you fill out the questionnaire. Strangers don't know you, and only when they see their own benefits will they act.
