為人處世，應如蝸牛，兩個觸角在前面探索前路，遇到阻礙，就縮回來一點，再向他方探索。蝸牛尚知此理，人們怎會不知呢？
Getting along with people and handling matters, you should act like a snail. A snail explores the road ahead with two tentacles, withdraws and changes directions when touching obstacles. As a snail knows the way of moving along, how do people also not know it?
