The canoekayak manufacturer tells you that in ancient times, people found that leaves and trunks would float in water, and found that the weight that leaves can carry is very small, and the weight that the trunk can carry is large. The thicker the trunk, the more weight it can bear. also bigger. The canoekayak manufacturer tells you that people have also found that the cylindrical trunk is unstable in the water, it will roll over, people will not be able to sit on it, and people cannot move on this cylindrical trunk at all.
Ngele ndlela, people use tools such as stone axes, stone adzes, and spades to flatten the round tree trunks. Kamva, it was found that it was more convenient to work wood with fire than with stone axes. Abavelisi bephenyane bakuxelela ukuba abantu baqabe isiqu ngodaka olushinyeneyo olumanzi naphi na apho kungafuneki kugrunjwa., uze utshise iindawo eziya kugrunjwa. Ngele ndlela, indawo etshisiweyo itshiswa ibe ngumaleko wamalahle, emva koko wagawulwa ngezembe lelitye, kulula. Yiloo ndlela i-canoekayak eyenziwa ngayo.
Umenzi we-canoekayak ukuxelela ukuba kukho irekhodi kwincwadi yakudala yaseTshayina “Incwadi yoTshintsho-Xixi” ukuba “iinkuni ezisikiweyo liphenyane”, nto leyo ethetha ukuba iphenyane lenziwe ngomthi osikiweyo. Ngaphakathi 1958, kwafunyanwa amaphenyane amathathu eWujin County, IPhondo laseJiangsu. Ngokutsho kophando, babengamaphenyane ukusuka kwiXesha laseNtwasahlobo nelaseNkwindla kunye neXesha laMazwe alwayo. Babenjalo 11 iimitha ubude, 0.9 iimitha ububanzi kunye 0.4 iimitha ubunzulu. Ngoku bakwiMyuziyam yeMbali yaseTshayina.
