In 2009, in order to allow more middle and high-storey users in the city to enjoy a comfortable and healthy bath life, Gomon developed a built-in balcony wall-hanging water tank with forced circulation, with the micro circulation pump embedded in the bottom of the water tank, and a number of patents were applied for it. Since then, Gomon has become a solar energy company that applies enamel water tanks to the balconies of high-rise residential buildings in the city.
