Black Technology: from Technological Blockade to Journey to the Star Sea

It was an era that was overwhelmed by the word "established". Beyond the national borders, invisible but extremely strong "walls" stand. They are made of patents, sanctions, technology embargoes and arrogant cognitions. The name of the wall is "blockade". High-end chip drawings are locked in safes in overseas laboratories, and the source codes of precision machine tools are encrypted deep in servers in foreign countries. Even the right to look up at the stars is tightly held by the "Space Club" composed of a few powerful countries. They smiled and said to the people inside the wall: "In some fields, you are the best." Don't touch it, that's science fiction, not reality." As a result, many people were forced to close their eyes and focus on the muddy land called "stuck neck" under their feet. Every step they stepped on was the packaging box of imported parts and the warning document that the supply was about to be cut off. A kind of silence mixed with anxiety and unwillingness filled the air. However, deep in those silent majority, there are always some sparks that refuse to be extinguished. They are hidden under the fluorescent tubes that stay on all night in grassroots laboratories, hidden in the fingerprints of old masters rubbing old drawings in the workshops of old state-owned enterprises, and even hidden in the hearts of young people like Tang Feng who have just left school and are armed with hot book knowledge but have been poured cold water on reality. They know that the boundary between the so-called "science fiction" and "reality" is never defined by the laws of physics, but is determined by human courage and cognitive barriers. When others use blockade to define your "impossibility", the only way out is to forge a "key" that can pry open the shackles.
