In 2017 I visited Portugal to participate in the 14th annual international conference on “Hands-on Science”，HSCI2017. That occasion was my first visit to the beautiful Iberian peninsula; the amazing land and culture impressed me deeply. Staying in Braga, which is located in the northern area of Portugal, for several days, I learned how people enjoy their relaxed life in this wonderful country. Best of all, I met Professor Manuel, who has devoted his efforts to science education for a long time. We share many common ideas about science education; to work with him is a delightful experience for me.
