From being listed in the "entity list" of export control by the U.S. Department of Commerce, Google suspended some business transactions, to the 90 day delay in the implementation of the U.S. ban on Huawei, Huawei has frequently become the focus of public opinion in the past week.

In this "eventful autumn", on May 21, Ren Zhengfei, the founder of Huawei, was interviewed by several media at Huawei headquarters in Shenzhen. In more than two hours of dialogue, Ren Zhengfei, 75, responded positively to a series of hot questions about Huawei with 42 answers. He talks about America, cooperation, development and family. He speaks a lot, one word, one word, all full of positive energy and patriotism. He also witnessed the pioneering spirit, broad mind, indomitable fighting spirit and selfless quality of the long-standing founder of Huawei. His feelings are full of struggle, unyielding, tolerance and dedication, which not only shows the style of Huawei people, but also highlights them It shows the great spirit of the Chinese nation and the Chinese people to work hard, to advance in the face of difficulties, to innovate, to forge ahead, to persevere and to be fearless of power. In this fight against US trade bullying, Huawei has set an example for Chinese enterprises and the Chinese people.

Huawei people tell us that the glorious tradition of hard work and self-reliance cannot be lost. The Chinese Chinese are China's China refuse to be cowed or submit to the 54 Movement. In general, Xi Jinping, general secretary of the Chinese Communist Party, delivered a speech on the 100th anniversary words of the 100th anniversary movement. He pointed out that the Chinese people and the Chinese people understand from the struggle practice that China's social development, the revitalization of the Chinese nation and the happiness of the Chinese people must rely on their bravery to fight for it. No one will give us a bright China. Therefore, we need cooperation and support from others, but more importantly, we need Huawei people's self-reliance spirit, to strengthen themselves, and to strengthen their own development foundation, so as to prevent people from "choking their necks" at critical times.

Huawei people tell us that we should not lose the sense of preparing for the unexpected. In the face of unprovoked pressure from the United States, why can Huawei take it easy? The key is that Huawei has a strong sense of crisis, and started to build its own "spare tire" as early as 10 years ago, which is probably not expected by the American bully. Huawei's outstanding performance this time has also fulfilled the old Chinese saying of "be prepared for no danger". At the same time, it reminds us of another saying: everyone has no future and no worries. Therefore, in order to realize the great Chinese dream of national rejuvenation, any enterprise, any person and any enterprise must enhance the awareness of risk prevention and build their own development foundation.

Huawei people tell us that we cannot lose the ideal and belief of selfless dedication and loyalty to serve the country. The country is tens of thousands of families, and the family is a small country. No country, where can I come from? At present, the theme publicity and education activities of "my country and I" are being carried out nationwide. Undoubtedly, Ren Zhengfei, 75 year old founder of Huawei, left his family behind for everyone. With his lifelong pursuit, he has taught a vivid patriotism education lesson for the whole society. My motherland and I are the relationship between children and mother. No matter how successful you are, everyone can never leave the cultivation of your motherland. A person can make his life more brilliant only if he has the ambition to serve his country, loves his country, and makes selfless contributions to his country and the people.

We are constantly inspired by Huawei's hard core spirit. Guangzhou Qingcheng (formerly Beijing Shenghua) is one of the major manufacturers that can provide a full range of acoustic emission products in the world. From the beginning, it broke the monopoly of imported products, and now its products are distributed in more than 20 countries around the world. Guangzhou Qingcheng has the production capacity of a full range of acoustic emission products, various types of system desktop / handheld / Internet of things / wireless / wired, all kinds of sensors intrinsically safe, explosion-proof and high temperature, etc. At the same time, it has created many firsts: the world's first USB communication acoustic emission system, the world's only data acquisition system for explosion prevention acoustic emission, and the world's first WiFi communication acoustic emission system. The world's only series of unattended Internet of things acoustic emission monitoring and alarm system. Qingcheng people have stumbled all the way, laughing and tears, but they are also growing slowly. As Ren Zhengfei said, "without scars, there is no rough skin and thick flesh. Heroes have suffered a lot since ancient times.".

Salute, unyielding Chinese Huawei! We should take the U.S. trade hegemonism into consideration. Ren Zhengfei and all Huawei people have fought for glory for the motherland, greatly increased the aspirations of the Chinese people, their broad mind, their fighting spirit and their patriotic spirit, which are worth learning!
