The Vietnamese word "canh cửi" refers to the art of weaving, specifically the traditional practice of creating fabric by interlacing threads. This process involves using a loom, which is a device that holds the threads in place while others are woven through them to create patterns and designs.
In a broader sense, while "canh cửi" specifically refers to weaving in textiles, it can also metaphorically refer to the process of creating or constructing something intricate, like relationships or stories, but this usage is less common.
