Cherish History, Strengthen the Nation through Science and Technology
September 3, 2025
September 3rd is the Commemoration Day of the Victory of the Chinese People's War of Resistance Against Japanese Aggression.
On this special occasion, let us pay tribute to the heroes of the War of Resistance!

Eighty years ago, flames of war raged and rivers and mountains were bathed in blood. Countless Chinese people built an iron Great Wall with their flesh and blood, finally ushering in the dawn of national rejuvenation. That epic written with faith has left us not only victory but also the spiritual fire of "self-improvement and resolute guardianship".

Eighty years later, "security" under peace has ushered in new battlefields: the stability of energy arteries, zero accidents in industrial production, and the sustainability of blue skies and white clouds. Guoke Hanhai continues the predecessors' oath with a beam of laser, making the spirit of the War of Resistance shine again in the journey of serving the country through science and technology.

From oil and gas stations deep in the desert to urban underground gas pipelines; from emission reduction outlets of incinerators to the top of chemical plant towers — for more than a decade, our laser monitoring equipment has shouldered "responsibility" for every risk early warning with millisecond-level response and micron-level precision. That red beam cutting through the night sky is the silent yet firm "charge bugle" of the new era.

During the War of Resistance, ancestors built "border-region-made" rifles under blockades; today, we have also broken foreign monopolies, developed original TDLAS laser absorption spectroscopy technology, and launched a series of products. The breakthrough from 0 to 1 and the expansion from 1 to N — every independent innovation is a response, inheritance and practical continuation of the spirit of the War of Resistance.

Eighty years have passed, the original aspiration of "guardianship" has never faded, and the background color of "self-improvement" has become brighter. Guoke Hanhai will continue to deepen laser technology, guard industrial safety with a beam of light, assist the "dual carbon" vision with a beam of light, and let the spirit of the War of Resistance burn perpetually in the magnificent picture of high-quality development, illuminating the starry sea of national rejuvenation!
On this special day,
let us cherish history and comfort the martyrs' spirits.
