The book donation in the community has always been relatively rough. Some friends often complain about not being able to win the prize, and the winning address has a high rate of similarity. Judging from the low participation of the winning users in the community and the community, it can be seen that many of them are Pure wool users.
In order to accurately deliver the benefits to the real developer partners who need it more , it is an important purpose of this revision.
When the number of people is full , the lottery will be drawn, for example: 5 copies will be given away, and if 5 people participate, the prize will be given away directly
There is a threshold for the lottery, and you need to pass the community points to participate in the book donation
Sharing = points, you can easily get points by posting and sharing various technical content, learning resources, etc.
Finally, friends who need the current benefits can take action:
