Shandong Museum is no problem, the interpreter we booked on Trip.com is very regrettable. During the May Day holiday, I was afraid that the on-site interpreter would not be able to make an appointment, so I booked on Trip.com in advance. Was told that 300 yuan per person. After arriving, the museum staff told me that the explanation in the museum was about 80 yuan per person. Money is not a problem, the following focus: because it is not a professional explanation in the museum, the business problem is relatively large. 1. Like to brag about yourself. Knowing that we have limited time, the tour guide spends a lot of time introducing how professional he is, who has received, how popular, etc. We do not care about content. 2. The explanation content is boring. Can't grasp the key points, it is like the class in school that has heard sleepiness. 3. Time control is very bad. More than half of the time has passed, and our progress is less than one-fifth. As a result, I can only rush past the back, which is very regrettable. 4. The explanation is not clear. The guide's Mandarin is not standard and speaks slightly faster. The group friend who listened to the explanation with us reminded him more than once and hoped that he would speak slower because there was a 9-year-old child in the group listening, but it did not improve. Later, we met the professional interpreter of the museum of other groups, the young lady wearing a suit. It is very interesting, we listened to others' explanations. It is recommended that you ask the professional explanation of the museum, after all, time is precious and not to be wasted.
