When Tai Shan and his father, Baba, fly kites from their roof and look down at the crowded city streets below, they feel free, like the kites. Baba loves telling Tai Shan stories while the kites--one red, and one blue--rise, dip, and soar together. Then, a bad time comes. People wearing red armbands shut down the schools, smash store signs, and search houses. Baba is sent away, and Tai Shan goes to live with Granny Wang. Though father and son are far apart, they have a secret way of staying close. Every day they greet each other by flying their kites—one red, and one blue—until Baba can be free again, like the kites.
