As the new school term begins and boarding students are assigned lockers, a small fingerprint padlock has become a campus favorite. Few know that this compact lock is made in Zhongshan's Sanjiao Town by tech firm eLinkSmart.

A national-level "Little Giant" enterprise (specializing in niche, refined, distinctive and innovative products), eLinkSmart relocated from Shenzhen city to the town in 2020. It focuses on the R&D, production and sale of smart home and IoT devices.

From January to August, the company's smart gateways, set-top boxes and smart locks generated over 200 million yuan in export revenue, up 11.1 percent year on year.

Zhongshan's favorable business environment has laid a solid foundation for eLinkSmart's steady growth. Over the past 3 years, the company has invested more than 32 million yuan in technology upgrades, greatly boosting both its production capacity and efficiency.
