There may be no better way to understand a region, a country, than to let its doctoral students show you around, first their work, then their favourite haunts. Our day with them began quietly, in a cool molecular-biology corridor where they spend their hours coaxing answers out of the invisible world. From there it spilled outdoors, into an unhurried wander down a hundred-year-old shopping street, and finally gathered, as the best days in Wuhan do, around a steaming tray of crayfish, sleeves pushed up, fingers stained happily red, everyone talking over everyone. What ties those three scenes together is more than good company. It’s a whole food system, quietly on display: the microbes that keep crops and soils healthy, the paddies where this city’s cherished summer catch is raised, and the streets and tables where all of it finally comes home.

Morning: microbes, and the students who study them

We spent the morning at Huazhong Agricultural University (HZAU), one of China’s leading agricultural universities, in the company of the graduate students who work in its National Key Laboratory of Agricultural Microbiology. If that name sounds abstract, the corridor makes it wonderfully concrete: wall after wall of research posters on the microbes that fix nitrogen, fend off crop disease, and turn waste into fertiliser. It is the diligent, invisible workforce underneath every field we had walked through earlier in the trip, and here were the people who spend their days getting to know it.
