TAL Education (NYSE:XRS), a K-12 after-school tutoring services provider formerly known as Xueersi, announced today it will inject 150 million yuan ($24.79 million) of strategic investment in childcare portal Babytree. The acquisition of Babytree will help TAL to include pre-school children into its target customers. TAL has acquired education site Kaoyan.com for 50 million yuan last year. In addition to the baby and maternal site Babytree.com, Babytree operates pre-school education brand Mika, and seven mobile apps. Online education became a hot topic in China since last year with a wave of education startups raised fundings.
