1. Li Zhizao's Geographic Map of the Great World has seven original editions, all of which are kept abroad. The Vatican Library Collection 1: 6 screen is complete, with three Jesuit seals on it, and it is not colored. This was sent back to the Vatican by Jesus from China. 1938, published by De Lixian in his book Map of the Chinese World by Father Matteo Ricci. This map is not framed, but Roman letters are marked on the back of the map. Tibetan version 2: Like Tibetan version 1, it has six screens, no coloring and slight damage. Jesuits brought it back from China. Not yet announced. The six screens of Kyoto University in Japan are complete and in color. All three Jesuit seals in the picture have been scraped off, probably during the period of Japan's prohibition of religion. Compared with the first edition of Vatican Library, there are some minor typographical errors. This version should have been brought to Japan by missionaries from China, and was framed and colored after being introduced to Japan. Although this version is rarely eroded by moths, the periphery of each screen is seriously damaged, and many words are blurred in many places on the paper. The six screens of Miyagi prefectural library in Japan are complete and colorful, and its source is still unknown. Some people think it may be the relic of the first astronomer of the Tokugawa shogunate and the author of Xiang Zhen Li (1639- 17 15). Others think it is more likely to be Data Masamune's collection (1567- 1636). The damage of this collection is not too serious, but it has been damaged by moths many times, resulting in the lack of pictures and texts, and there are many stains on the paper. The Cabinet Library of Japan has been insured for 19 years (1734), and this map is kept in Nagasaki. In the second year of Yuan Wen (1737), it was included in the Momijiyama Library of Edo (Shogunate Library) together with many local chronicles of China. 1873, the map was transferred to the newly-built cabinet library together with other books of Momijiyama Library. This collection is not bound and well preserved, and the degree of moth-eaten and damage is very slight. Unlike the other two Japanese collections, this painting has no traces of coloring. /kloc-in the 6th century, the former Clemens College had a Jesuit Clemens College in Paris. 1682, King Louis XIV of France authorized this college to become the Royal College, which was later renamed the Grand Louis College. 1946, Philip, England? Robinson bought a great set of general geographical maps from Clemens College. 1974, this map was shown to the public in the Sino-Japanese Map Exhibition held by the British Library. 1988, this picture was taken by Henry? Shearer is enough. 199 1, again in Sotheby's catalog. The whereabouts of this painting are unknown now. This picture has not been mounted. The Observatory of the University of Bologna in Italy has two screens (the first and the sixth). In the late 20th century, when people remounted the two screens of the world map, they mistakenly put one of the screens of the astronomical map drawn by the German missionary Tang Ruowang (1591-kloc-0/666) between the two screens, which made the whole circle look very strange. 2. 1603 version of Two Instruments is now displayed in Liaoning Provincial Museum.

3. 1608 There is only one picture book of the Forbidden City, which is kept in Nanjing Museum.

4. Japanese picture books are kept in Jian Ye Library, the affiliated library of Tohoku University.
