章 89: Quality Control Process

It had been five years since Cheng Yunfeng started Rock Technologies. It was already a success to have persevered for five years as a high-tech company. In his own humble words, he had achieved a small success by this point in his life. At less than 40 years old, he was worth more than a hundred million and could freely enjoy life.

The cleaning robot that Rock Technologies had developed was now in its third generation. Customers' reactions were good and the product had accumulated total sales of over one million units. It had the second largest market share in the nation.
