Before departure, a WhatsApp, WeChat, or Line group will be created to provide meeting instructions. During the trip, the communication app will also be used to provide guides or meeting times, which is very convenient. Although this tour is long, the time allotted for each attraction is not excessive. However, Dr. Wang tried his best to give everyone enough time and provided ways for everyone to visit, dine, or use the restroom smoothly. The explanations on the bus and the detailed lecture at Oxford University were also very thorough. Throughout the trip, appropriate time was given for explanations and rest. He is a 100-point excellent tour guide, highly recommended! The only minor flaw was that before the meeting, the instructions for the meeting time and location clearly stated that seat selection on the bus would be based on the check-in time and number, first come, first served. We arrived at 7 AM, and the number of people at the bus stop was very clear and obvious at that time. As time passed, a tall young man arrived first and checked in according to his arrival order. At this point, we raised an objection, but it was only one or two people, so we let it go. We also informed him who arrived first and who arrived later, and everyone subsequently checked in with him. We clearly heard him give everyone the sequence as 1, 2, 3, 5, 6, 7, 8, and so on. When it was time to board the bus, another woman (possibly one of the local travel agency members, as there were three groups that day, and she also helped direct) told four older women to board first. Everyone asked if it shouldn't be in the order of number 1, number 2, and she actually claimed they were number 0?! We clearly did not see these four older women when we arrived at 6 or 7 AM, and number 0 was not mentioned when registering on the check-in sheet. The registration order was clearly audible to everyone. Only when it was time to board the bus did she say there was a number 0 cutting in front, and they even took the very front row of seats on the left and right! If there are connections, personal favors, or VIPs who need seats arranged, please don't make it so obvious and unpleasant. It ruined the good mood for the outing early in the morning! Further evidence is that when the tour guide first called names for the meeting, he also started from family number 1, 2, 3, and it was one of the older women who said they were family number 0. Only then did the tour guide include them in subsequent roll calls. This shows that generally, no one uses 0 as a check-in sequence. It is suggested that next time you want to reserve seats for guests, do not arrange them so haphazardly.
