He has been engaged in the strain electrical measurement industry for nearly 50 years. Despite being nearly 70 years old, he remains true to his original aspiration. With his outstanding ability and innovative development concept, he continuously researches and develops products with independent intellectual property rights, breaks the monopoly of foreign electrical measurement, sets a benchmark for domestic brands, and enables the enterprise to grow into an invisible champion in China's strain electrical measurement industry. He is Wu Dechang, the chairman of Guangdong Hualan Haidian Measurement Technology Co., LTD. (hereinafter referred to as "Hualan Haidian Measurement").

Since the establishment of Hualan Haidian Measurement, Wudechang has always been driven by a strong sense of responsibility and mission, boldly exploring and innovating, with the goal of achieving leading high quality, thus keeping the enterprise at the forefront of the industry. At present, the products produced by this enterprise, such as resistance strain gauges, pressure sensors, weighing and force sensors, as well as automotive dynamic weighing systems, have been exported to the Asian, European and American markets and have achieved a certain market share.

Set sail for entrepreneurship with dreams in your heart
In 1997, Woodchang's career blueprint unfolded a new chapter at Guangzhou Huanan Co., LTD., where he served as the deputy general manager of the project and shouldered the heavy responsibility of scientific and technological research and development. Three years later, he rose to a higher level and became the manager of Huanan Sensor Factory in Guangzhou Economic and Technological Development Zone, standing at the forefront of reform and facing the huge waves of The Times.
At this time, Wood, who was in his forties, worked very diligently, had an advanced mind and was a "tech maniac". Whenever there were difficult problems with some sensor devices, it was always him who worked hard to break through them. With a spirit of diligent research and development, Wood has accumulated various experiences in the research and development of electrical measurement products.
At the beginning of the 21st century, under the wave of reform, state-owned enterprises were restructured one after another. Having accumulated a great deal of experience, Wood Chang took over this state-owned enterprise and embarked on a journey full of unknowns and challenges.
In 2003, on the basis of acquiring Huanan Sensor Factory, Woodchang established Dongguan Hualanhai Electronics Co., LTD. The company mainly produces high-precision resistance strain gauges for sensors, strain gauges for force measurement and weighing, sensors for daily weighing instruments, portable static and dynamic wheel axle weighing systems for automobiles, high and low-speed dynamic weighing systems, weighing and charging systems, pressure sensors and transmitters, high-temperature melt pressure sensors and their supporting instruments, etc.
However, scientific research is not something that can yield results simply by researchers devoting themselves wholeheartedly; it is subject to various objective constraints. At the beginning of his entrepreneurial journey, Wood often encountered problems such as a shortage of funds, a lack of talents, and a sluggish market. Each problem was like a mountain peak standing on his path forward, requiring him to summon up tenacious perseverance and outstanding wisdom to climb.
With the dual identities of a "Beihang University student" and an "electrical measurement expert", Wood never gives in in the face of difficulties. That year, like most young entrepreneurs, Wood often started everything from scratch, being both a boss and a salesman, a designer, a repairman and a porter... Two years later, Wood Chang's sensor sales were growing steadily. He rose from setbacks and completed the initial accumulation of experience and capital.
On November 4, 2015, Wu Dechang renamed the company "Guangdong South China Sea Electronic Measuring Technology Co Ltd."
"If you do it, do it first." This is a phrase that Wood often mentions. In recent years, Hualan Haidian Measurement has been able to establish its brand in the global market, relying on its innovative technologies and products that aim to be the best. Over the years, Hualan Haidian Measurement has continuously increased its investment in technological research and development and product quality, with its annual R&D investment accounting for more than 10% of its total sales. Up to now, Hualan Haidian Measurement has over 60 patents and has passed multiple professional international certifications such as CE, RoHS and OIML.
After 13 years of entrepreneurship, Hualan Haidian Measurement was approved to be listed on the New Third Board in 2016 due to its outstanding performance.
To become a globally leading provider of Hualan Marine electrical Measurement to build an internationally renowned brand, surpass peers, lead the world, and realize the goal of serving the country through science and technology is the dream of many entrepreneurs, and it is also the dream of the generation of entrepreneurs like Woodchang. Nowadays, he feels that the dream of his youth is about to come true. Compared with his initial mindset when starting his business, he admitted that making money might have been his top priority at that time. But now, the sense of achievement from conquering one "bottleneck" technology after another is the greatest motivation for him to move towards the future.
The path of striving has no end. Despite having weathered the storms, Wood Chang still has not been content with the status quo.
In Wood Chang's long-term strategic plan, Hualan Haidian Measurement aims to achieve a global leap from domestic substitution to export to Europe and America. Under his planning, Hualan Haidian Measurement's international layout has been both forward-looking and solid. Since its establishment, Hualan Haidian Measurement's products have been directly competing with Japanese and American enterprises in the Chinese market and the European and American markets, which has laid a solid foundation for the company's internationalization.
After years of development, most of Hualan Haidian Measurement's products are exported to Europe and America. Some of the exported products have reached the technical standards of similar products in Europe and America, achieving complete interchangeability with foreign products. It has basically achieved the top position in the industry in the Chinese market and brand recognition in the international market. At present, the products of Hualan Haidian Measurement are basically distributed in Europe, North and South America, Southeast Asia, the Middle East and other regions. The company's international trade has accounted for 30% of the total business volume of the company.
Despite this, the internationalization path of Hualan Haidian Measurement has not been smooth. Language barriers, cultural differences, and market competition - each one poses a new challenge. However, Wood often firmly believes that only by embracing the world can Hualan Electrical Measurement's dream go further and its path in the international market be broader.
Hualanhai not only possesses an international strategic vision and layout, but also our R&D innovation, talent team, and local services are gradually achieving internationalization. Recently, we are also preparing to acquire foreign companies to enhance our technical service capabilities in the international market. Wood often says.
To build a world-class enterprise, cultural construction is the soul of the enterprise's development, the source of team cohesion, and the guarantee for standing in the world's strong forest. All along, Hualan Electrical Measurement has advocated the values of openness, innovation, responsibility and win-win, and has been striving to create a dynamic and creative working environment. Wood often believes that the power of culture can inspire the potential of every employee and jointly promote the internationalization process of the enterprise.
