Zhuang Liu had arranged for an indoor swimming pool, which, despite its limited space, was very warm. It was still rather cold now, and outdoor swimming pools were not quite suitable for Tan Rou's training.
Tan Rou first went to check out the swimming pool, where she discovered a faint layer of steam rising above, making the entire space comfortably warm.
Although she knew that water surfaces emit steam in winter, this was a swimming pool, not a natural spring—how could there be steam?
Tan Rou squatted down, reached out, and touched the swimming pool only to find that the water inside was actually warm, not very hot, but significantly warmer than tap water from a faucet.
"The water is actually heated!" Tan Rou asked in surprise, "You didn't burn something underneath, did you?"
Zhuang Liu came closer and explained, "I indeed installed a geothermal heating system under this swimming pool so that it won't feel cold even when swimming in winter."
