No, just one brother; he's the person who prompted my mom to found that primary school in the Atayal mountains. So I used to refer to him as kind of the pioneer of the experimental education because when he was 8, my mother did a primary school, and when he was 7th grade, my mom did an alternative experimental school on the junior high and when he was in the 10th grade, my mom did a senior high, extending the junior high principle. So he basically led, just by growing up, the alternative school movement in Taiwan.
