After reading Lao Wu's travelogue, I realized that I was too lazy and didn't spend enough time with the chipmunks. Starting next semester, I will participate in more of the chipmunks' lives. But speaking of which, New Zealand is indeed good. When I came out, New Zealand was also a research site. Unfortunately, due to some reasons, I was unable to conduct on-site inspections. Let's find another opportunity in the future.
