Jinan is famous for its spring, and "Colorful Baby" is based on water droplets representing spring. The smiling expression and open arms express the hospitality of the people in Spring City, and the running posture reflects the happy and positive atmosphere of the Spring Festival. The idea of "colorful" comes from the gorgeous scene of water droplets refracted by sunlight. At the same time, "colorful baby" has also been integrated into a deeper cultural connotation. "The color of the rainbow also symbolizes the rich and colorful cultural life of Jinan people. The image of water droplets is like a budding seed, representing life and vitality."
