To quickly memorize the poem "Viewing the Sea of Cangshan," employ mnemonics, which are memory aids that help in retaining information. Mnemonics can be particularly effective for poems due to their structured nature. One approach is to create a story or a visual image that encapsulates the poem's content. For instance, visualize the poem's imagery, such as the sea of Cangshan, and associate each line with a unique element of that image. Another technique is to use acronyms or phrases that begin with the first letter of each line. For example, if the poem starts with "High mountains," "Vast sea," "Clouds," and "Sun," you could create the mnemonic "HVS." This method is based on the concept of chunking, which involves breaking down information into manageable pieces, making it easier to remember.

Research supports the effectiveness of mnemonics in memory retention. A study published in the "Journal of Experimental Psychology: Learning, Memory, and Cognition" found that participants who used mnemonics to learn a list of words were significantly better at recalling them compared to those who did not use mnemonics (Craik & Lockhart, 1972). This study demonstrates that mnemonics can enhance memory performance by organizing and linking information in a way that is easier to retrieve. Additionally, a meta-analysis of various mnemonic techniques revealed that mnemonics can improve memory for both factual and procedural information (Bower, 1991). These findings underscore the utility of mnemonics as a tool for memorizing complex and lengthy texts, such as poems.
