At a time when the increasing amount of haze weather affects the living environment of humankind, the development of clean energy is a responsibility not only of the photovoltaic industry but also of humanity as a whole. It is not just the re-emergence of the clear sky, but the creation of a home for harmonious civilization for future generations. As a few industries in china that are among the world's leading players, the photovoltaic industry has occupied half of the world for years. Countless people are here, dedicated to youth and sweat. Lungi, as the leader of this huge army, has been through the wind and the rain. At the onset of the industry, deep-tilled monocrystals are routed, with strength to withstand internal and external shocks at the onset of the industry's collapse, and with a rapid recovery of the industry to optimize the distribution of the industrial chain. As the backbone of the industry, responsibility and mission have been throughout the development of lungi. We are well aware of the responsibilities and the need to accelerate the development of the photovoltaic industry and to increase access to abundant, low-cost clean electricity at advanced technology and reasonable prices. "the mountains are bluer and the water greener" is a dream shared by the lungi. In the future, lungi will, as always, be engaged in the legacy of the pv spirit and the innovation of downscaling technology, re-constructing clean and green energy with the advanced pv technology, striving to disperse the fog within a decade, working with the pv industry, observing the blue sky with society
