You can cancel it. If you cancel in the lottery, you are not allowed to participate in the lottery for 3 years.
Lottery tickets are similar to lottery tickets. Yaohao means that people get a number before choosing a house, and then decide the order of choosing a house according to the lottery. For example, if there are 50 houses to be shaken, and there are 100 people who are qualified to shake, 20 people have the right to participate in the priority shake. In other words, these 20 people will draw lots first. Of course, the result may be that there is a room or no room. If 15 of these 20 people shake the house, then the remaining 80 people will shake the other 35 houses.
