RYB

Ryb Education Inc

A provider of early childhood education in China, RYB runs kindergartens and "play-and-learn" centers for children from infancy to age six, along with educational toys and at-home learning materials. Co-founded in 1998 by Cao Chimin and Shi Yanlai, the company grew from a single play-and-learn center in Beijing into one of the country's largest early-education networks. Its name comes from the primary colors red, yellow, and blue — the building blocks of art and creativity.
