Buddhism

The world's oldest firm was Kongō Gumi, a Japanese temple builder founded in 578 AD. A Baekje artisan built Japan's first Buddhist temple at Prince Shōtoku's request, and it raised temples for 1,400+ years over 40 generations — until a 2006 takeover ended its run.

In Buddhism, Avalokitesvara (觀世音) was shortened to Guanyin (觀音) due to Tang dynasty Emperor Taizong (李世民). Under Chinas name taboo custom, the character 世 from the emperors name could not be used publicly. This practice also renamed government offices, influencing Korea.
