Introduction and appreciation of a journey of dust;

A Journey to Dust is an anthology of popular science by Grandpa Gao Shiqi. It first tells the life experience, habits of bacteria and their relationship with human beings, then tells the interesting knowledge of scientists on the classification of bacteria and their activities in the human body, and finally tells the stories of scientific articles such as papermaking and ironmaking.

This book vividly describes and introduces "dust travel" through various rhetorical devices, portrays the characteristics of cells, bacteria and protein, and reveals the laws of their survival, life and function. In the book, the author introduces the methods of dust control in detail with delicate brushstrokes, and vividly describes the complex process of evolution from single cell to multi-cell, which is unforgettable.
