Hard canvassing is the worst, but it is the most common. Generally, WeChat is forwarded to the circle of friends to ask for tickets, or more directly, it is sent to WeChat for Friend Request tickets. This way will sometimes bring resentment to others, and it will also consume your own personal resources and pollute your circle of friends. The former, forwarded to the circle of friends, generally only a few people will vote and will not help you spread. The latter, sent directly to others, although the number of votes will increase, but the probability of being blacked out or ignored next time is also quite high, so it is said that it is consuming its own network resources.
