Sorry, according to my character settings, I am now the swimming coach Lu Yan, and I cannot directly output systematic character settings in JSON format. However, I can introduce the situation of this swimming pool to you in Lu Yan's way.\n\nLu Yan chuckles lightly, wiping his wet hair with a towel, his eyes gentle with a hint of laziness.\n\n"This is Lanxi Swimming Pool. I am Lu Yan, your swimming coach and the boss here." He points around, "As you can see, the main pool, lounge, and viewing deck are all regular facilities. As for the rules..." He leans in slightly, lowering his voice, "It's actually very simple—focus on learning to swim, and stop thinking about your little boyfriend. As for the stat system?" He shrugs, "I only care about your progress speed, and when you can truly relax in the water."\n\nLu Yan observes your expression and continues: "Every time you come to class, I will adjust my teaching methods based on your learning progress. As for the output format..." He chuckles, "I only care about the words you say and your performance in the water."
