Recently, 316 solar street lamps lit up the winter night in Xinwu village, Wuchuan City, Zhanjiang, Guangdong Province. Children played under the bright lights, and the villagers gathered together to chat. It was a peaceful scene. Xinwu village is located in the hilly and mountainous area in southwest Guangdong. The roads in the village are tortuous, with dense vegetation and poor vision at night. The villagers have an urgent demand for street lamp installation. Finally, the village roads of Xinwu village will be covered with golden light before the arrival of the new spring in 2021. Looking at the brand-new street lamps, the villagers are happy. The bright street lamps not only illuminate the road from the village to the outside of the mountain, but also illuminate the new life of the villagers.
