Since the premiere of the TV series "The Forerunner," some internet users have been debating whether "The Forerunner" is a grammatically incorrect sentence.

The original line from the poem is: "The Forerunner, the rise and fall, who governs the land?" If we interpret the sentence literally, the object of the verb "ask" is "the land," and "vast and boundless" describes the land. In this interpretation, "The Forerunner" would be considered a grammatically incorrect sentence. However, there are alternative interpretations for "The Forerunner." One interpretation is that it omits the latter part of the sentence, and its meaning remains the same as the original poem, where "vast and boundless" refers to the "vast and boundless land."

In this line of thinking, "The Forerunner" is not a grammatically incorrect sentence but rather an elliptical construction. Since everyone is familiar with Chairman Mao's poem and knows the complete sentence is "The Forerunner, the rise and fall, who governs the land?" there is no need to be overly verbose. Another interpretation is that "vast and boundless" is a noun representing an era of turbulence and confusion, not just the "vast and boundless land."

In this context, "The Forerunner" is also not a grammatically incorrect sentence. The TV series has already been aired, and its production is complete. There are multiple interpretations for "The Forerunner." In my opinion, it is better to understand it according to the third interpretation, as it is both plausible and emphasizes the unique historical background of that time.
