Eating a light meal on the way around Beijing and Tianjin is called "pinching". However, after textual research, it is found that "striking the tip" should be "striking the fire"
Fogg's Listening to the Rain in Qing Dynasty (volume 1 1) notes: "Today, people are engaged in service and have a meal in a Japanese shop, which is called sharp tip. It goes without saying that the meaning of this word, or midway is between accommodations, is a mistake of "between" and "sharp". I'd like to order "Cui Hua seeks happiness", which means "fire in the fire" mentioned by Zhongdun. See also the novels of people in Song and Yuan Dynasties, saying that the meal on the way is called' striking fire', and because of the word' fire', it is naturally mistaken for' sharp'. "
This is also common in novels and zaju. The 60th chapter of Water Margin: "Let's talk about Wu Yong and Li Kui jy. They went to Beijing for four or five days. Every night, they go to the store to rest and light a lamp on the road. " Article 8 of the Biography of the King of Yue: "Now, the guys we are going to take are looking for water in droves and asking Zhuang Ding to make a fire and cook." Master Wang Yuan's The West Chamber Wedge: [Servant Cloud] Xiao Ye. Let's leave early and make a fire in front. "
The "striking a fire" here is to strike a stone to make a fire. Firemaking tools include: fire sickle, flint and tinder. Sickle is a piece of raw iron sheet, about ten centimeters long, three or four centimeters wide and half a centimeter thick. Quartz stone took it, hit it violently and collided with the iron sheet, so it sparked and attracted the tinder beside the hand. The fire was made successfully. Velvet is made of cattail sticks mixed with carbon, nitrate and sulfur, and is usually packed in bags. If the sickle is made skillfully, the upper part of the iron sheet will be made into a leather bag that can hold tinder. You can also hang it around your waist and take it at any time. Replacing "cooking" with "making a fire" is a common metonymy in spoken English. For example, use "working in the fields" instead of "building houses" with "laying bricks".
