Children aged 0-6 can attend Xiaobu's early education class. My sister began to study with Xiao Bu six months ago. Xiao Bu pushes some repetitive two-syllable lessons or nursery rhymes every day, and her sister imitates them with her mouth open. She also sticks out her tongue and does some body movements from time to time. I feel that such audio games can stimulate her consciousness of independent imitation, which is quite good.
