In ancient Chinese,"Qi" was a pronoun that referred to a certain person, thing, place, etc. It could also mean "among them","one of them","that","this", etc. Below are a few common explanations of "Qi" in ancient texts: 1 means to refer to a certain person: for example, in the Analects of Confucius, Gongye Chang: "Zi Gong asked,'Is there a word that can be used for life?' the master said,"how can you forgive? Don't do to others what you don't want others to do to you." 2 means to refer to something. For example, in Dream of the Red Chamber, the Lady Dowager said to Baoyu,"These are some Shichahai flowers. Take them back and don't get blown away by the wind." Among them,"Shichahai Flower" referred to something. 3 means that it refers to a certain place: such as Lin Chong in Water Margins: "Where is the sober tonight?" Willow shore, morning breeze, waning moon." Among them,"Willow Bank" referred to a certain place. In the Water Margins, Wu Song said,"This is Liangshan Lake, and we will live here for the rest of our lives." Among them,"here" referred to Liangshan Lake,"namely" referred to "one of them", and "convenient" referred to "that". 5 means to refer to oneself: For example, in the Water Margins, Song Jiang said to himself: "I was originally a small official in Tokyo City who was demoted here because of a crime." The "I" referred to Song Jiang himself. It should be noted that the word "qi" in ancient prose was sometimes used in combination with other words, such as "qigu" for "reason","qizhen" for "true","qizhi" for "peculiar", etc. Therefore, when reading ancient prose, one needed to understand its meaning according to the specific context.
