I booked the Erlitou Xiadu Site Museum on Trip.com. I thought that the professional teacher who could talk about Xia history there should be, but I didn't expect to meet the Erlitou archaeological team, and found the teacher Guo Zhenya of Bronze Jue. Teacher Guo spoke like a number of Zhen, full of emotions and memories of those cultural relics. The captains of several archaeological teams are familiar with them, and there are also contacts with archaeological experts, so we feel very kind and admired when we introduce those archaeological people on the wall to talk about their friends. Teacher Guo also brought a lot of treasures, replicas of the milk nail baron, etc., let us feel the "temperature" of the cultural relics up close, and was honored to meet the current archaeological captain to introduce the students to the possible students, and suddenly feel that these archaeological Junjies are so close to us. Thank you Ctrip for providing such a good explanation service. The explanation service on Trip.com has been very good several times, this time it is overjoyed!
