Tom,
”You adhere to the rules in solo practices, so that in a fight, where rules don’t work, you will still have some semblance of skill.”I think we’re on the same page. I guess in writing one always has to take into account that the reader is always going to take everything literally and at face value. But we probably need to continue to always add in the above disclaimer when discussing solo training principles.

A) these songs were written in the late 1800s so modern Chinese doesn’t always work. And more importantly B) the number of syllables in a word is the most important deciding factor, so in this case 2 syllables is all that could be used.

Of course the triangle stepping looks different in application but the guidelines work with any step- forge step, advancing step, retreating step, and even backstepping, like you can see in the bear application.
Here’s a few more songs from Joseph Crandall’s translations of Shi Jidong’s 48 Bagua Songs:
“8. Xie Chu Cheng Ru - Diagonal Leaving, Straight Entering:
With footsteps firm and stable, seek adroit movement. By advancing, retreating, turning, and shifting, seek out the enemy's path. Walking follows the triangle. The toes grip the ground. Diagonal leaving, straight entering, is wonderful and unlimited.
9. Xu Jin - Continuous Advancing:
Develop an offensive posture, the enemy can not move back. Continue advancing with strikes that are difficult to evade. Step and advance the body, then step to the front. The hands, feet, and body must be one and arrive together.
10. Lian Zhui - Continuous Chasing:
I advance. If the enemy retreats, I must follow. One step or two steps, I am continuously stepping to follow. Closely press the enemy so there is no way for him to flee. Continuously advance, victory comes in one step.”
Diagonal leaving, straight entering; Straight leaving, diagonal entering
