With the philosophies of "diligence breeds success" and "sincerity wins trust", Hang Cheung Hong consolidated its position and explored new opportunities in the petrochemical industry.

The Group began to purchase raw materials in China while actively expanding its presence in the China market.

Under China's open policy, the Group began developing innovative, high-tech chemical products, expanding its product range and creating its own brands.

The Group set up its first factory, Hang Cheung Petrochemical Factory, in Buji, Shenzhen.
