There is a lyric in Peking Opera "Don't make jokes at this time": three people climb (step) the gate of hell together, and their writing style is different. Is it "crawling" or "stepping"?

According to the information I have, the word "climb" in the lyrics of "Three people climb (step) to the gate of hell together" in Peking Opera "This is no joke at this time".

In this lyric, "climbing" means that three people climb the gate of hell together, and "stepping" means that three people step on the gate of hell together, which is inconsistent with the context. Therefore, "climb" is a more appropriate writing.
