The book "Travels in the Central Parts of Indochina (Siam), Cambodia and Laos (Volume 2 of 2) in 1858, 1859 and 1860" was written by the distinguished French explorer and traveler Henri Mouot. In this book, he details his travels and research in Southeast Asia, where he visited Siam (modern Thailand), Cambodia, and Laos in the mid-19th century. Muo talks about his impressions of local life, culture and nature of the countries he visited, as well as about meetings and observations with local residents. This book became an important source for understanding the history and culture of Southeast Asia in the 19th century and represents an addition to European knowledge of the region at the time. Muo's journey to Indochina was important both for science and for cultural exchange between East and West. His observations, descriptions of local customs and spiritual monuments have made his book an invaluable resource for modern researchers and anyone interested in the history of Southeast Asia.
