What does do zan mean in taewkondo?

Two women

I don't know who came up with "two women." Do san is the second pattern in ITF Taekwondo. The name of the pattern, Do-San, is a pseudonym of the patriot Ahn Chang-Ho (1876 - 1938). The 24 movements represent his entire life which he devoted to furthering education in Korea and the Korean independence movement.
