Draw a simple version of Guangfu food map, first draw the longitude and latitude lines in proportion. Then determine a coordinate point and draw the road with a pen first.

Then we should draw buildings according to the road and mark all kinds of delicious buildings with different symbols. Remember that the proportion of latitude and longitude depends on the size of this picture. Point out the direction and draw a rough block ratio (the gap between a wide street and a small street must be drawn). Better have a name. At the crossroads, you should mark the main buildings. With the name and direction (the direction of the building), you should be able to understand it.
