Looking for a sitter for two elementary school kids

Hello sitters! I'm looking for someone fluent in Chinese & enjoys teaching kids. The role would involve creating and administering a Chinese culture curriculum - food, stories, games, art, music, etc. - to 2 girls (7 and 5yo). The goal is to get them to improve their verbal Chinese language while learning more about the culture, place and people. This would occur after school 2x per week (days are flexible) from now through mid-June 2027 and would run from 3:30-6pm in our home (near Seger Park in Center City Philadelphia). I'm looking for these classes to be taught in Mandarin and someone to encourage them to respond in Mandarin.
