🏢 Who We Are & Strategic Heritage
Chengdu, Sichuan, the birthplace of the “Shu” Nation, is the land of abundance. It has rich natural gas resources. Thousands of years ago, the ancient Shu civilization originated here. Under the protection of the sun bird, it lit the first bonfire of human civilization and sounded the first trumpet to open up the land.
When the wheel of history progressed to the year 2002, a gas company named “TYQT” was established here. “TY” stands for Taiyu Gas, reaching the Top of Mount TAI; “HJ” represents HongJin Gas, embracing a bright future. Driven by the goal to make profound contributions to industrial advancement across Greater China, we provided a steady stream of vital gas supply for continuous modernization.
