Zhao Haiyang pointed to the building entrance, slightly straightened his body, and proudly introduced:

"This is also the number one research center of our Group. The five-leaf electric fan that laid the foundation for the development of the Hanhua Group was born here."

"Now, decades have passed, the equipment in the research center has been updated and iterated, and people have changed batch after batch, but the spirit of our predecessors has been passed down."

"The country's first set of two million-ton ethylene equipment, the first million-ton water press, the operational design drawings all originated here."

Hearing this, Xu Yun and the others immediately showed a hint of respect on their faces.

This practice of retaining laboratory 'designations' is very common in China.

For example, the renowned Sinopec.

Its first laboratory to develop oil pumps has also been preserved and is still maintaining high output today.

There's also the Zhongjing Medical Laboratory in the Central District of Ke Da.

It was the first medical laboratory established after the Southern Relocation of the Science and Technology University and remains incredibly vibrant today, even producing a paper for The Lancet last year. The group walked straight for several hundred meters, passed a few buildings, and finally arrived outside a one-story building.

"Ladies and gentlemen, this is our comprehensive research center."
