There is no famous saying. The transliteration of "Wo Zijishode" is what I said myself.

He came from a friend on the Internet who posted a composition that seemed to be about middle school students: "Smart". The composition begins with a quote from a famous person:

Real wisdom is when people control technology, not the other way around. ——Wo Zkishuod

Which country is this "Wo Zkishod" from? What academic background? The teacher who graded the exam must not have known something, so he may have searched the Internet and found no such person! Then he had no choice but to ask without shame, and then the student might have to tell the truth: "Wo Zijishuode", that is, "I said it myself."
