Firstly, drawing. The pencil is one of the commonly used tools for drawing. It can leave delicate and precise lines on various types of paper, and different line thicknesses and color depths can be produced depending on the hardness of the pencil (from H to B). Pencils are mainly used for sketching, outlining, and drafting in drawing, which can quickly express the artist's creative ideas and thoughts. Secondly, writing. The pencil is an essential tool for writing. In the process of writing, the pencil can help us to structure our thoughts, record and sort ideas, and quickly capture our ideas and inspiration. Additionally, pencils can also be used for writing formal texts and articles, especially when it comes to修正需要修订和编辑的内容时，铅笔可以轻松地擦除或修改错误的内容。 Thirdly, design, drafting, and engineering. In the fields of design and drafting, the pencil also plays a very important role. Designers can use pencils to quickly sketch their ideas and design thoughts on paper, which allows them to explore different design solutions in the early stages. In addition, in the engineering field, pencils are often used for tasks such as drawing sketches, annotations, and marking, helping engineers better understand and analyze engineering problems.
