What group has Tianshui Yonghong Factory changed into?

I would like to ask why Tianshui Yonghong Equipment Factory was renamed Tianshui Huatian Electronics Group. According to the information provided by the paper, the reason why the equipment factory is called Tianshui Huatian Electronics Group is as follows:

1, development needs: Tianshui Yonghong Equipment Factory was founded in 1969, and its original products were semiconductor parts, transistors and solid-state circuits. With the development of the times and the change of the market, in 2002, its product fields were adjusted to integrated circuits, power modules, power devices, LEDs, integrated circuit sealing and testing equipment, materials, spare parts and so on. In order to highlight the company's new positioning and product range, it was renamed Tianshui Huatian Electronics Group.

2. Company expansion and diversified development: Tianshui Huatian Electronics Group has several holding or wholly-owned subsidiaries at home and abroad. This shows that the company has experienced expansion and diversified development in the past few decades. The name change is to better reflect the scale and diversified business scope of the company and better represent the electronics industry involved in the group.
