Changshu Showroom is renovated from a factory building and designed with industrial style.  It covers an area of 3000 sqm and is adjacent to the factory.  The visiting route from production line to the finished product display not only meets the one-stop tour experience, but also has a comprehensive view of the product production process.  The layout of the showroom is divided into upper and lower floors, with a complete range of products and clear display effect.
