How to classify brush, pen, pencil, crayon, watercolor and sketch?

The landlord, as the name implies, can answer the following questions:

1. Writing with a brush: writing with a brush dipped in ink.

2. Pen words: words written with a pen.

3. Pencil characters: refer to characters written in pencil.

4. crayon drawing: refers to a picture drawn with crayon drawing.

5. Watercolor painting: refers to a painting made of pigment and water and dipped in a pen.

6. Sketch: refers to simply using pencils and lines.

If the landlord wants to practice pen writing, Baidu searches the top ten classic pen brands in the world (with the origin of pens and simple selection and maintenance methods), and has a very complete set of pens and selection methods, all of which are my personal experiences, hoping to bring you help.
