On November 5, students of the extra-curricular class on science with Yuyao Fengshan Primary School were observing butterflies' habits in their Butterfly Studio. The school opened this scientific practice base, namely the “Butterfly Valley” in the campus with the purpose of cultivating students' interest and enhancing their hands-on ability. Students are able to learn butterflies’ habits by way of feeding, observing, recording, photographing and producing specimens.
