Mobile Toilet and Yuehai Yingtong

Currently, there is no evidence indicating a direct business relationship between 'Yuehai Yingtong' and mobile toilets. Here is a detailed analysis:

Foshan Yuehai Yingtong Supply Chain Co., Ltd.

Founded on March 29, 2018, this company focuses its core business scope on supply chain services and management, including commodity sales and freight forwarding. Supply chain services typically involve the optimization and integration of logistics, warehousing, procurement, and other links. Commodity sales cover the circulation of various physical or virtual goods, while freight forwarding emphasizes the intermediate coordination services for cargo transportation. From its business scope, it does not involve the design, production, installation, or sales of mobile toilets. Mobile toilets are special sanitary facilities whose research, development, and manufacturing require specific technologies, equipment, and qualifications. The business logic of mobile toilets differs significantly from that of supply chain services and commodity sales, so it is unlikely that this company will engage in mobile toilet-related businesses.

Foshan Yuehai Yingtong Intelligent Technology Co., Ltd.

Founded on June 11, 2020, this company's business scope mainly includes metal door and window manufacturing, metal structure manufacturing, and the manufacturing of other electronic equipment. Metal door and window manufacturing and metal structure manufacturing typically serve the construction industry, involving the production and installation of doors, windows, steel structures, and other products. The manufacturing of other electronic equipment may cover the assembly and production of various electronic products. None of these business areas directly involve mobile toilets. The manufacturing of mobile toilets not only requires metal structure processing capabilities but also needs to integrate professional capabilities in sanitary facility design, sewage treatment technology, and other aspects. However, this company's business scope does not reflect relevant technical reserves or business directions.

Comprehensive Judgment

The business scopes of the two main companies under 'Yuehai Yingtong' do not explicitly mention mobile toilet-related businesses. Moreover, from a business logic perspective, their existing businesses have no direct connection with the manufacturing, sales, or services of mobile toilets. Therefore, it is currently impossible to determine that 'Yuehai Yingtong' has business dealings or cooperation with mobile toilets. If further confirmation is needed, it is recommended to inquire about its latest business dynamics through official corporate channels or authoritative business information platforms.
