The newly-founded company was located in Building 401 at the intersection between Yannan Road and Zhenhua Road in Futian District. Since Chen Chengwu was not very expert at the research, development, and production of gas detectors and alarms, he invited his former workmate, engineer Su Yihua, to draw a draft for him.

Su Yihua asked him to send a product to the National Anti-explosion Center for testing and gave him a letter and told him to contact a person in charge. The first batch of products were qualified upon testing.

1991

During the years from 1987 to 1991, the company’s total sales was less than RMB 100,000 and it had a debt exceeding RMB 100,000. Its products were not salable. All the founders except Chen Chengwu left the company, which survived only by manufacturing cable insulating strips.

When Chen Chengwu knew that Su Yihua, who drew a draft for him, planed to resign from the former employer, he immediately invited Su Yihua to join ExSaf. On February 3, 1991, Su Yihua led three persons to join ExSaf and worked as Manager in the company.

In August 1991, the stock market in Shenzhen crashed. In September, Shenzhen Development Bank stood out to become a pivot point levering the first bull market in the securities market history.

The company’s first portable gas detection alarm SS318

In 1991, the company only had one gas detection alarm with a special structure. Su Yihua led all employees to develop and design new gas detection alarms.

At that time, the area of the office leased was less than 100 square meters. It was divided simply into two sections, an office and a workshop, where there was no fan in it. Everyone worked hard and even worked overtime at night. A few employees shared a big burden of jobs, which were not divided. Nobody expected overtime pays. Under such conditions, the company’s first portable gas detection alarm SS318 was brought out. Later 90G detector and TON96 controller were developed and produced.

These persons were Kang Wei, Liu Qian, Xiang Jinhui, Zhang Yu, Huang Xizhong, and Su Yihua

Due to shortage of funds, ExSaf could not sell products by common means. Initially, it sold products by writing to potential customers to introduce the company and its products. After a customer wrote back to the company and expressed its interest in the company’s products, the company’s salespersons set off for the customer’s location.

Though we were short of funds for sales, we would go to customer’s location at the first time if a customer had a technical question or needed after-sales service. In this way, customers trusted us gradually.

The company’s sales amount was RMB 275,000 in 1991, RMB 1,040,000 in 1992, over RMB 2,700,000 in 1993, and more than 5 million in 1994.

In the same year, Shenzhen Development Bank’s stock price went up to RMB 63 from RMB 17 when it was listed.

A get-together at the dormitory in Donggualing in an evening in 1994

Initially, the company’s employees resided in peasant’s houses in a village at North Shaputou, Futian District. Later, because the company moved to a new place, they moved to peasant’s houses at Huanggang Village, Futian District. As the company had more employees in 1994, it rented half a floor of a building in the temporary housing area in Donggualing, Shenzhen and all employees lived there.

At that time, the most attractive thing for them was to stay together to eat, drink, and chat. Such get-together became the most unforgettable and exciting thing. During business trips, they made an appointment for evening get-togethers in Shenzhen when returned. Nobody cared about the shabby environment in the residence and they often got drunk in the get-togethers.

With the development of the company, these persons were sent to some other places in China several years later. Since then, they seldom stayed together.

So it invited a quality management system consulting company to train all managerial staff. The company also began to apply ISO9000 management system methods to all aspects.

At that time, only a few companies applied the quality management system. In 1996, China Paints (Shenzhen) Company was China’s first company which was ISO9000 certified.
