The book World Knowledge from Books published by China Map Publishing House is very good, except that only the first seven or eight pages introduce the whole continent in color. It is not a complete book that can introduce all countries and regions in the world (if there is one, it is not detailed). It is divided into six volumes: Asia, Europe, North America, South America, Africa and Oceania. It consists of three parts: text, pictures and maps. The text mainly introduces physical geography, area, population, nationality, history, politics, national flag and emblem, economy and people's life, folk customs, important cities and places of interest. Rich in content, concise; Maps include topographic maps of continents, administrative regions, major countries and cities, which are concise and exquisite, and show the general situation of geography, administrative regions, famous cities and place names of continents and countries in a more intuitive form; The national flags and national emblems of representative figures, landscapes, customs, buildings and other countries are selected in the picture. Highly recommended, rich in content, involving all aspects, very good.
