In Shanghai in June, the humidity of the rainy season was like an airtight net, wrapping Jukasa through the equipment warehouse of the sports center. She held a freshly printed purchase list in her hand. The edges of the A4 paper were wrinkled with sweat. On it were densely listed the training equipment to be replenished next month - 30 pairs of professional knee pads, 15 boxes of sports drinks, 8 sets of adjustable dumbbells, and imported non-slip slippers specially approved for the provincial team swimming team.
