First step, first take out a piece of white paper (or paper with horizontal lines is fine), use a black pen to draw a straight line on the white paper (you can draw it a little bit longer)
Second step, in the middle of the straight line you just drew draw a rectangle (you can draw it a little bit wider and a little bit taller).
Step 3, draw another shorter rectangle to the right of the one you just drew.
Step 4, draw another smaller rectangle to the left of the larger one.
Step 5, add some small squares to the three drawn rectangles to draw windows for the hospital.
No. Step 6, after drawing the windows, draw the door of the hospital.
Step seven, draw a cross on the building in the center.
Step eight, color the cross you just drew with a red pen.
The sketch of the hospital building is done.
