Answered. Mozi did not directly answer Zishuo’s question of which was the most important thing in pursuing a just cause at the beginning. Instead, he adopted a metaphorical approach, first using building a wall as a metaphor to explain it clearly. As long as everyone does their own work well, then they can clarify their views and accomplish a big undertaking. There is no priority in the work. Only when everyone performs their duties, does their best, and works together in unity can this undertaking be accomplished. OK.
