Generally, when you have spare space, you can draw some beautiful and bright colors, or draw some small animals, such as mice, cows, cartoon tigers, white rabbits, dragon girls, hibernating snakes, horses, lambs, naughty bobo monkeys, chickens, watchdog, innocent white pigs, or cats who are not in the Chinese zodiac, or draw some flowers and trees, or lanterns and firecrackers. Create your own couplets, anything related to the Spring Festival. The most important thing is to be true and draw with your heart. If you don't draw with your heart, there won't be this problem.
