Cities I’ve Been To Since 2012 (continuously updated)
I’ll update and preview the cities I’ve (will) been to right here!
（July 22, 2022）Due to the pandemic, I haven’t moved for 4 months, missed a May Day wedding, and missed getting our marriage certificate together on 520; we haven’t seen each other for 4 months either.
Now everywhere requires a recent 14-day Itinerary Card; I can produce my past 10 years of itineraries! Following the same logic as the Itinerary Card, brief pass-throughs aren’t counted, but transfers generally are. As of December 13, 2022, the Itinerary Card was discontinued.
From 2012 to July 2022, I visited 42 cities and made 259 trips (going from city A to city B counts as one; returning to city A makes it two). In 2019 alone I traveled 63 times. When I got these stats, I was quite shocked. Although I traveled a lot for work over the past three years and even visited 12 cities in Japan in 2019, I still didn’t expect the number to be this high. Why so many business trips? My first project’s main base was in Hangzhou, so from June 2019 to May 2020 I spent most of my time in Hangzhou. On my current project I lead three teams in Hangzhou, Shanghai, and Israel—Beijing is the only place without one; as an architect I also frequently need to attend reviews. I guess God thinks long distance suits me.
During my jointly supervised PhD between USTC and Microsoft Research Asia (senior-year internship in 2013 ~ PhD graduation in 2019), I often shuttled between Hefei and Beijing—quite a lot already for a student. I didn’t expect to travel even more for work afterward; in 2021 on Hanglv Zongheng I was ahead of over 97% of users. The remaining 3% were practically frequent fliers. One regret is that during my PhD I was too frugal and often reluctant to spend on tickets, so I saw my girlfriend very little. Another regret is that after trips I was often too lazy to write summaries; my memory is poor, and after a while I can only reminisce using photos and chat logs.
As of November 2023, I’ve been to 71 cities and taken 380 trips—29 more cities than a year earlier—mainly thanks to our honeymoon in Xinjiang after the wedding and my three months in the United States. “City” is a bit hard to define; in the U.S., using the county might be more reasonable. If I logged every cross-county movement, my U.S. count would add many more “trips” (moving within the Bay Area and Los Angeles-Irvine doesn’t really qualify as travel), and I probably couldn’t even keep track of them all.
Statistics as of May 2022, not updated
Of course, I don’t have permission to obtain base-station connection data from telecom operators. The itinerary data comes from ticketing records, business-trip records, etc. Since some tickets weren’t booked by me, some trips may be missing。例如，2014 年 6 月从 MSRA 结束实习回合肥本科毕业的时间已无据可查。According to the internship certificate covering July 9, 2013 to May 30, 2014, the date from Beijing to Hefei has been confirmed.

How many cities did I visit each year?
| Year | Trips |
|---|---|
| 2012 | 3 |
| 2013 | 10 |
| 2014 | 13 |
| 2015 | 14 |
| 2016 | 22 |
| 2017 | 26 |
| 2018 | 25 |
| 2019 | 63 |
| 2020 | 29 |
| 2021 | 45 |
| 2022 | 31 |
| 2023 | 87 |
| 2024 | 55 |
| 2025 | 43 |
How long did I stay on each trip?
The longest single stay was 325 days. In 2012, from February to the end of the year I didn’t budge from USTC. In the past 10 years, there were only 6 times I stayed put for more than 3 months. The most recent was a 130-day stay in Beijing (March 6 to July 13, 2022), second only to the 325 days without moving in 2012 and the 131 days from February 25 to July 5, 2013. No wonder I felt completely cooped up (the average stay lengths in 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 | Count |
|---|---|
| 1 | 93 |
| 2 | 19 |
| 3 | 12 |
| 4 | 9 |
| 5 | 4 |
| 6 | 3 |
| 7 | 1 |
| 10 | 1 |
| 14 | 1 |
| 19 | 1 |
| 34 | 1 |
You can see that most of the time I went to a single city and came back, but there were also times when I made a big loop before returning.

Afterword
My mom’s comment after reading this article:
Life is like a journey, traversing thousands of mountains and rivers and weathering wind and rain. Every stretch of scenery holds beautiful memories, and every storm calls for a positive response. What is most worth cherishing is meeting a like-minded partner on the road: to admire the scenery along the way together, to share joys and hardships, to stand together through wind and rain, to traverse countless mountains and rivers and tread through wild hills and forests, to reach the summit of happiness, to watch clouds roll and unfold and the sun rise and set, and to share the splendor of life.
