Reason for entering the industry: At the end of 1999, by chance, a friend said that there was a product that could generate electricity and light lamps by sunbathing. At that time, his mind immediately popped up with the scene of reading with a kerosene lamp every day when he was a child, and the wind always burned his hair. He thought to himself, wouldn't this solve the problem of mountain people and children like me who couldn't use electric lights? As soon as I thought of this, I resolutely chose to enter this industry and have been working there for 24 years. I have always been altruistic, persevering all the way, and loving it for a lifetime!
