Western numerology
Four thousand represents stability squared and magnified. Architects understand: the foundation determines the building's height. This is the number of empire builders who start with blueprints and end with skyscrapers. Here, methodical precision isn't boring—it's revolutionary.

Chinese numerology
Four thousand (四千, sìqiān) is avoided even by mathematicians in China. The homophone with 死 (sǐ, death) makes it taboo in business and architecture. Skyscrapers jump from 3rd floor straight to 5th. Tetraphobia conquers logic—culture defeats arithmetic.
