On Dec 7, the drone (无人机) club at Changji No 4 Middle School in Xinjiang got a 1:28 scale (比例) model of the Chang’e-6 lunar explorer (嫦娥六号月球探测器). The teacher told them about the explorer and then guided them on how to put the model together. The model was small but detailed (精细的). It had more than 10 parts, such as a robotic arm (机械臂), a lander (着陆器) and a solar wing (太阳翼).
