In January 2024, we arrived in Istanbul, Turkey, the junction of Europe and Asia. Thanks to Turkey for his enthusiastic directions. Although he pointed the wrong way, he wasted his time for us and helped us inquire about the bus. I am also very grateful to Mr. HAYRI for his hospitality and taking us to visit various tourist attractions, which made us feel like we were in China. Thanks to all the companies for their hospitality and taking the trouble to pick us up and drop us off every day. Looking forward to our next meeting.
