Understanding a country, starting with its history, understanding a country's history, starting with visiting its museums. Thank you to the Chinese commentator for his lively explanations. Many improvisations and overtime service are really great. Understanding Singapore's past, present and future is of great significance to our trip. After the visit, it is easier to communicate with the local people, because the understanding of cultural background is the cornerstone of all communication. This trip is the most meaningful of my trip to Singapore!
