Final answer:
The question appears to be about Ji-li and the Red Guards but actually pertains to Gil-Dong and his anticipation of the government's trap with the letter. Gil-Dong is smartly forewarned and thwarts his enemies' plans by disappearing in a cloud, leaving his adversaries discomfited. His actions also shed light on the social injustices of the era.
Step-by-step explanation:
You asked about what Ji-li thought would happen if the Red Guards found out about the letter. However, I believe there might be a mix-up in names as the references provided do not mention a character named Ji-li, but rather focus on the character Gil-Dong. Gil-Dong, in the recounted tale, was aware of the deceit and danger that awaited him upon accepting his new rank from the government. The posting of the letter on the Palace gate contained a cunning plan, where the betrayal was embedded in an offer of honor.
Contrary to the expectations of the plotters, Gil-Dong was prepared for the trap set at the ceremony. His expectations were to be thwarted by culminating in a supernatural escape that discomfited his enemies. Gil-Dong was able to anticipate the treachery and thus prepared an avoidance strategy. This element of surprise and cleverness demonstrates his shrewdness and the idea that he foresaw the common fate for such an uprising figure, given the context of the time and circumstances. The struggles and triumphs of Gil-Dong also provide insight into the societal structure and norms during his era, particularly in how individuals born to concubines were regarded and the plans to prevent their rise to power or recognition. This character navigates through these challenges, illustrating his ability to overcome vendettas and injustices, much like the old hag prophesizes about his future greatness.
