"The Heart of Nature: Natural History in Daily Life" starts with plants from the botanical garden of Peking University. It leads readers to observe, record, and understand plants by paying attention to the plants around them. The book introduces the terminology used to describe plants, including naming, chirality, invasive species, plant ethics, and the cultural content of the relationship between humans and plants. It encourages readers to get close to nature, find the names of plants, discover their stories, gradually establish their own natural archives, and embark on their own journey of natural history. It provides vivid materials for people to understand plant species, plant protection, and nature education, and also serves as a sample for nature enthusiasts to quickly familiarize themselves with unfamiliar environments and accurately identify local species.
