You can fold a piece of cardboard or brightly colored paper into a simple origami, and then draw the elements of spring, such as flowers, birds and sunshine, with colored pens or ballpoint pens. Then write "Happy Spring Tour" and "Good Spring Tour" and make a simple and beautiful spring tour recommendation card.
If you want to make cards more complicated and beautiful, you can search related DIY tutorials online, learn some origami and hand-made skills, and increase your creativity and interest.
