Wongsojoyo Valen, (1623, ?) was a factory worker in Hanoi.
Wongsojoyo believed in Confucianism.
She was at the time the top fortune in the world and lived an opulent life, richer than a whole country. She was considered a standard citizen of their society, with as much power than most of the people. People saw Wongsojoyo as cultivated, eager to read and learn when possible, and mastering writing, which she did for friends. She was weak, and fell ill all the time. She was considered strong-willed, a leader at heart.
