This summer, the fourth-grade children of Wahaha Bilingual School went to Qiandao Lake to participate in the water survival training course, which is a classic course customized by Wahaha Bilingual School for fourth-grade children, and invited the famous traveler "Lao Ji" to lead the team. "Lao Ji", formerly known as Xu Chenghua, is a global traveler, writer and documentary director with rich outdoor survival experience, guiding children out of the familiar daily comfort zone and learning water sports skills. Under the guidance of the teachers, they seriously studied the skills of kayaking. On the basis of experiencing and feeling the water, they learned various kayaking skills such as front oar, back oar, sweeping oar, getting on and off the boat, tying the boat row and so on in various team games, and learned how to save themselves in the water and how to survive in the wild environment. Finally, all the children independently completed the kayak voyage of 15km.
