Cities I've Visited Since 2012 (Continuously Updating)
Let’s update and preview the cities I have (or will have) visited here!
(July 22, 2022) Due to the pandemic, I haven’t moved for 4 months, missing a wedding on May 1st and missing getting our marriage certificate on May 20th. We haven’t seen each other for 4 months.
Now, everywhere requires a travel card for the past 14 days, but I can show my travel for the past 10 years! Similar to the logic of the travel card, short stays in certain places are not counted, but transfers are generally included. As of December 13, 2022, the travel card has been phased out.
From 2012 to July 2022, I have visited a total of 42 cities and traveled 259 times (traveling from city A to city B counts as once, and returning to city A counts as twice). In 2019 alone, I traveled 63 times. I was quite shocked when I got this statistic. Although I traveled a lot for work in the past 3 years and visited 12 cities in Japan in 2019, I didn’t expect it to be this many. Why so many business trips? My first major project was in Hangzhou, so I spent most of my time there from June 2019 to May 2020. Currently, I lead three teams in Hangzhou, Shanghai, and Israel, but not in Beijing. Additionally, as an architect, I often need to attend seminars. Perhaps God thinks I’m suited for long-distance relationships.
During my joint Ph.D. training at USTC and Microsoft Research Asia (from my senior year internship in 2013 to my Ph.D. graduation in 2019), I frequently traveled between Hefei and Beijing, which was already quite a lot for a student. Unexpectedly, the number of business trips increased after starting work, with my travel frequency surpassing 97% of users on Flight Manager in 2021. The remaining 3% must be frequent flyers. I regret being too frugal during my Ph.D., often reluctant to spend on tickets, resulting in limited time with my girlfriend. Another regret is often being too lazy to write summaries after trips. My memory isn’t great, and over time, I can only rely on photos and chat records to recall.
As of November 2023, I have visited 71 cities and traveled 380 times, an increase of 29 cities compared to a year ago, mainly from our honeymoon trip to Xinjiang after our wedding and my three-month trip to the United States. The term “city” is somewhat difficult to define. In the U.S., counties might be a more reasonable equivalent. If I record all trips across counties, my U.S. trips would count as many more “travels” (traveling within the Bay Area and between Los Angeles-Irvine doesn’t really count as travel), and I might not remember them all.
Statistics chart from May 2022, not updated
Of course, I don’t have the authority to obtain base station connection data from telecom operators. The travel data is collected from booking records, business trip records, etc. Some tickets weren’t booked by me, so some trips might be missing. For example, the time when I returned to Hefei after finishing my internship at MSRA in June 2014 for my undergraduate graduation is untraceable. According to the internship certificate from July 9, 2013, to May 30, 2014, the date from Beijing to Hefei has been confirmed.

How long is each trip?
The longest stay was 325 days, from February to the end of 2012, without moving from USTC. In the past 10 years, there have been only 6 times when I stayed in one place for more than 3 months. The most recent was a 130-day stay in Beijing (from March 6 to July 13, 2022), second only to the 325 days in 2012 and 131 days from February 25 to July 5, 2013. No wonder I felt so stifled (the average stay days for 2019-2021 were 6.0, 12.6, and 8.5 days, far below 130 days).
How many cities did I visit each time I left Beijing?
| Number of Cities | Frequency |
|---|---|
| 1 | 85 |
| 2 | 19 |
| 3 | 10 |
| 4 | 9 |
| 5 | 3 |
| 6 | 3 |
| 7 | 1 |
| 10 | 1 |
| 14 | 1 |
| 19 | 1 |
| 34 | 1 |
As you can see, most of the time I returned after visiting just one city, but there were also times when I made a big loop before coming back.

My mom’s comment after reading this article:
Life is like a journey, traversing thousands of mountains and rivers, experiencing winds and rains. Every scene holds beautiful memories, and every storm has a positive response. The most cherished part is meeting like-minded companions during the journey, who can share the scenery along the way, endure hardships together, and sail through storms. Together, they traverse mountains and forests, reach the peak of happiness, and enjoy the clouds rolling and unfolding, the sunrise and sunset, sharing the splendor of life.
