Our country has experienced difficult years in the past period of history. At that darkest moment, that is, at the beginning of 1920, Mr. Li Dazhao, Mr. Chen Duxiu and others began to contemplate the issue of Party building. Mr. Cai Hesen, who studied in France, clearly proposed that the “Communist Party of China” should be established. At that time, with the help of the representatives of the Communist International, intellectuals in many places in the mainland of our country established early party organizations. Until July 23rd, 1921, the first National Congress of the Communist Party of China was held in Shanghai.

At that time, our country was still a disaster stricken semi colonial and semi feudal Eastern power. There was a proverb: history is like a ship, carrying the memory of modern people to the future. And this memory still plays an important role in the memory of our modern people. So in the decades after the founding of the people’s Republic of China, we continued to be vigilant in times of peace, vigorously developed science and technology, economy, education and so on, and made today’s us look new.

On this lucky day, Hong Kong and Macao, China, returned to the embrace of the motherland one after another, that is, on July 1, 1997, the people’s Republic of China resumed the exercise of sovereignty over Hong Kong, ending a century of British colonial rule over Hong Kong.

So far, the two sides of the Strait have worked together to drive economic development. Under the leadership of the Communist Party of China, our Shanghai port and Shenzhen port have successively become world ports, making non negligible contributions to the world economy.

And this is also inseparable from the silent persistence of our personnel in the construction machinery industry. The Chinese people uphold the quality of hard-working, high-rise buildings leap from the wasteland, and the countryside is also changed. We should thank the Communist Party, but also the grass-roots working people who move forward bravely at the grass-roots level.

The tooth base is the guarantee of our infrastructure, and the bucket tooth is the front of our forward car. Here we recommend several products:
