On 2015 New Year's day, Zigong Shang Mei Culture and Art Co., Ltd. and Hongkong merchants reached a contract to customize 2 Chinese long dragon lanterns with a length of 20 meters. According to the contract, the two dragons are made in Zigong, Sichuan, transported to Shenzhen by train container, and then shipped to Hongkong. Considering that the customs formalities are cumbersome and the installation costs are high, Shang Mei does not send installers to Hongkong to install them. 

Merchants are instructing the installation under the written instructions of Shang Mei company. After 15 days of intense and orderly construction, Zigong Shang Mei Culture and Art Co., Ltd. delivered the color lights perfectly, and the customers also successfully installed the circuit instructions through the graphic and text.
