What is the representative work of The Root of Baiyangdian Poetry Group?

The root of Baiyangdian Poetry Group 1969 has gone to Baiyangdian to "jump the queue". During the period of 197 1~ 1972, he wrote eight long poems such as March and Doomsday, Baiyangdian, Orange Fog and Abyss Bridge. What I have seen so far is only March and the end, and the remnants of Baiyangdian.
