Why Can't I, the Great China, Make a Photolithography Machine?

Lin Bei, who became an international student after traveling through time, found that he was invited to participate in a variety show for college students around the world. However, he was treated maliciously by the program crew, who deliberately used Longguo's inability to build high-end lithography machines as an excuse. And this also inspired Lin Bei's attribute of a country-protecting madman. He angrily said on the spot, "Why can't I, a great China, build a lithography machine?" However, college students from all over the world laughed at it. "Give the Dragon Kingdom another 50 years, the photolithography machine technology will not be able to catch up with the Yingjiang Kingdom!" "Don't waste your efforts. Even if I give you the blueprints, the people of the Dragon Kingdom won't be able to build a lithography machine!" "The drawings and structures are all bought, and the Kirin chip cannot be considered domestically produced at all!" At this time, the domestic light system has arrived! Lin Bei decisively committed suicide and returned to Long Kingdom resolutely. A few months later, a paper on 1-nanometer lithography machines was published, shocking the world!
