The rise of dragons, service personnel and other issues.

This question is so broad. . When building a community, first, not too big. Pedestrians have stride limits, and different pedestrians have different strides. If the community is too big, it will definitely lead to a dead end; Second, try not to create a fork in the road, because pedestrians will turn at random at the fork in the road. Although there is an algorithm, it cannot be guaranteed in case; Third, make rational use of roadblocks, such as using roadblocks or middle courtyard doors, to reduce the scope of pedestrians' actions; Fourthly, if heroes are used reasonably, the summoned heroes will have pedestrian functions in one way or another. For example, Confucius can play the role of fortune teller, scholar, musician, tax collector and so on, which is very powerful. However, this can only be a small-scale role. If the community design is unreasonable, the protagonist is very helpless. .
