Ding Xin's face is full of people.

Not much. Ding Xin Science and Technology Group was established in 1998 with a total registered capital of over1600,000 yuan. It is a private scientific and technological enterprise group integrating intelligent product research and development, general contracting of engineering construction, commercial trade, agricultural industrialization and other diversified operations. At the end of the group, people will be brushed, but those who stay at the end are elites, so there are not many people who brush. The business of the company's subsidiaries involves four major fields: engineering, trade, science and technology and agriculture.
