A difficult maze with many and dense lines.
Steps to make a maze:
1. First roughly draw the area of the entire maze, draw the size of the area, and then divide it into several area blocks;
2. Set up the entrance and exit, and then draw a small area starting from the entrance. Determine in your mind how many exits there are in this area. There is no need to draw a road first and then fill in the rest, as it will be easy to see through. .
3. Consider the whole, how many passages there are, and which exit of the small area block you are drawing is connected to the passage. Remember to mark the exits with R and W to prevent confusion;
4. Repeat as above to fill each area block.
