Celebrating National Day
As the first breeze of golden autumn gently sweeps across the land of China, and the bright five-star red flag flutters proudly against the blue sky and white clouds, we usher in another glorious day — the 2025 National Day. On this joyous occasion of national celebration, Guoke Hanhai joins hands with the whole nation to extend the highest respect and sincere blessings to our great motherland.


Looking back, 76 years ago, the founding of the People's Republic of China was like a rising sun bursting forth in the east of the world, illuminating the path for the Chinese nation to move forward. From a state of extreme poverty to the world's second-largest economy, from "being unable to produce a single automobile, aircraft, tank, or tractor" to possessing a complete industrial system, from being blockaded and isolated by foreign powers to playing an important role on the international stage, China's development journey is an epic of strenuous struggle.
In those arduous years, countless people with lofty ideals marched forward courageously, sacrificing their lives and shedding their blood for national independence and people's liberation. On this ancient land, they left behind their firm footprints and unyielding figures.
Qian Xuesen overcame numerous obstacles to resolutely return to China and devote himself to the "Two Bombs, One Satellite" cause, forging an indestructible shield for China's national defense security.
Yuan Longping cherished the "dream of enjoying the cool under rice plants," worked diligently in the fields, and solved the food problem for hundreds of millions of people with his sweat and wisdom.
Wang Jinxi led oil workers to shout the heroic oath "If there are conditions, we will move forward; if not, we will create conditions to move forward" at Daqing Oilfield, providing strong impetus for the industrial development of New China.
It is the selfless dedication and tenacious struggle of these predecessors that have forged the backbone of today's China.
In the journey of the new era, science and technology have become an important force driving national development and protecting people's safety. As a leader in the field of laser monitoring technology, Guoke Hanhai has always adhered to the concept of "Serving the Country through Science and Technology, Innovating for the People," applying advanced laser technology in various fields and contributing its own strength to safeguarding national peace and prosperity.

Celebrating National DayIn the chemical industry, our laser gas monitoring equipment acts as loyal guardians, constantly safeguarding the safety of production frontlines. Through high-precision laser spectral analysis, it can quickly and accurately detect leaks of hazardous chemicals — even extremely tiny leaks can be identified in a timely manner. This provides reliable guarantee for the safe production of enterprises and effectively avoids major losses caused by delayed leak detection in previous chemical accidents.


In the energy sector, targeting key links such as oil and gas pipelines and LNG storage and transportation, Guoke Hanhai's laser monitoring system realizes real-time monitoring of parameters such as gas concentration and pressure. Whether in remote desert oilfields or busy urban pipelines, it can ensure the safe and stable transportation of energy.
For example, at a large LNG terminal, our equipment successfully warned of a potential leak risk, promptly notifying staff to take measures. This avoided a possible safety accident, ensuring the smooth supply of energy and the safety of life and property of nearby residents.
