It is built by Wang Dewen, famous as “Grandpa Amu”. He is regarded as a modern Lu Ban. While many admire his creative hands, what truly stands out is the traditional Chinese mortise and tenon(榫卯) skill he follows, making this bridge so special. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 The mortise and tenon skill is a smart and traditional wood-joining method with a history of over 7,000 years in China. It connects two wooden pieces by shaping one end into a tenon and cutting a matching hole called a mortise into the other piece. When the tenon is placed into the mortise, the pieces fit closely together. This amazing skill doesn’t require any metal part or glue but shows a strong and flexible(灵活的) connection. In fact, besides bridges, the skill is used in wooden buildings and furniture(家具) to help them stay fixed and balanced, even when temperature changes or earthquakes happen. The Palace Museum that uses millions of mortises and tenon connections is a famous example. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 Not only does this skill make strong buildings, but also shows the wisdom of traditional Chinese workers. Smart designs can be seen in every piece of work. All the wooden pieces must be cut with great patience and carefulness so that they can be locked into places perfectly, which also shows the deep thinking of traditional Chinese builders. They believe that humans should get along well with nature. So when building things, they choose to use wood, a natural material. This way, they can create what they need while still respecting nature. No wonder this skill is still used today. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 Although modern buildings often use concrete(混凝土) and steel, the mortise and tenon skill is still found in high-quality wooden furniture and the repair of historic buildings, reminding us how strong and lasting something can be when it is built with wisdom, patience and care. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 ( )1.

Known for its beautiful sound and lovely shape, it has enjoyed lasting popularity through the ages. The modern guzheng usually has 21 strings made of steel or silk covered with nylon(尼龙). When someone plays it, it produces a clear, bell-like sound that is bright, joyful or sad. This quality, along with its different playing methods, gives the instrument strong expressive power. That’s why its music has been played in royal palaces and among the general public equally. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 The stories about the beginning of the guzheng are different. One story suggests that it changed from the 25-stringed instrument called the se(瑟). According to the story, a se master had two talented daughters who loved playing the instrument. When he became too old to play the instrument, he wished to pass it on, but both of his daughters wanted the instrument. Finally, the master broke the instrument into two parts. One part had 12 strings and the other had 13 strings. To his surprise, the new instrument had a soft and beautiful sound, and he named it zheng. This seems to be supported by the Chinese character for “zheng”, which puts together the symbols for “bamboo” and “argument”. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 The guzheng became popular during the Spring and Autumn Period and reached its top in the Tang Dynasty. Over time, guzheng music developed into different styles, each with its own features. In recent years, more and more guzheng clubs and studios have appeared throughout the country. Meanwhile, the instrument has caught the attention of a growing number of learners around the world. There is no doubt that the guzheng will continue to win even more hearts. 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 词汇盘点 · 素养积累 The guzheng, a traditional Chinese instrument, has a history of over 2,500 years. 　1　 its beautiful sound and lovely shape, it has been popular through time.
