On March 8, 2022, a delegation led by the Third Construction Co., Ltd. of China Construction Eighth Engineering Bureau visited our company for investigation under the leadership of Huang Feng, the director of the technical center of the unit, and Tang Chao, the chief engineer of the decoration company.

Shen Hongdong, a senior engineer of the company's new energy industry, cooperated with managers Mao Chunfeng and Yang Guangsen of the sales department to receive them. Manager Yang Guangsen of the Sales Department introduced the development and product application of Lishida to the leaders of the Third Construction Company of China Construction Eighth Bureau. During this period, Director Huang Feng learned in detail about the use and sales cases of Lishida's new energy products in the construction industry. In particular, Shen Hongdong, a senior engineer of the company's new energy industry, answered many technical questions and suggestions on the use of rechargeable industrial mobile power supplies one by one.

After a detailed understanding of the product, Director Huang Feng said that the product is very suitable for temporary power consumption and flexible operation on roads and bridges, construction sites. They strongly agree on improving work efficiency and improving the safety of temporary electricity use. At the same time, they also highly affirmed the use of this new energy product to replace fuel fired generators to reduce on-site construction noise and carbon dioxide emissions, as well as the use cost of on-site extension lines and reduce the risk of power consumption for the stay lines. Director Huang Feng said that the country is currently implementing the "dual carbon" goal of reducing emissions, and CSCEC Group is one of the largest construction groups in China. The implementation of the "dual carbon" emission reduction goal proposed by the country has the right to propose and implement requirements in the field of building decoration. The use of clean electricity instead of traditional fuel power generation equipment is itself a practical measure to promote the realization of the "dual carbon" emission reduction goal.

Manager Mao Chunfeng of the Sales Department introduced in detail the advantages and use cases of the company's products used in the engineering decoration industry to visiting Chief Engineer Tang Chao of the Third Construction Decoration Company of China Construction Eighth Engineering Bureau, including the mature application plans and good feedback obtained by Shenzhen Branch of China Construction Decoration Group Co., Ltd., China Construction Oriental Decoration Co., Ltd., and Northwest Branch of China Construction Decoration Group on our company's products. Chief Engineer Tang Chao has conducted detailed research on various cases, and proposed the requirements for establishing intelligent management of on-site charging for decoration projects. Detailed records of relevant technical indicators have been made. Chief Engineer Tang expressed confidence in introducing our company's new energy industrial mobile power supply for decoration work, eliminating potential safety hazards in on-site wire pulling operations, and improving work efficiency. At the same time, we highly recognize the on-site (non electrified) construction scheme proposed by CSCEC Decoration Co., Ltd. Shenzhen Branch.

Subsequently, leaders of China Construction First Group visited the workshop to visit the production process of mobile power products in the new energy industry, and made a detailed understanding of the product's use functions.
