The first time I felt the power of team working is in the Tetonia，1/10/2020. That's the first long distance race we attend，15classic skiing race. The weather makes the race become special and petty cold. I'm really afraid of cold. But that day I am not aware of it. When we ready to start，it began to snow，and it got bigger and bigger. The big snowflakes made us lose the direction. At that time I try to find the right track，and I heard Mei shout at me，"I can't see the track，the snow is so big". I'm ahead of her，and I shout"follow me，Mei，I can find the track". And then we skied together，when we met our coaches，Christi and Rachael，they said"good job，girls，work together". And then we know our did are right. After 5k，the snow stopped，Bur I feel pretty terrible，because my legs are so weaken. Mei said "follow me，Simona，we can do it". "Yes，I said" I just follow her，keep the same pace with her… When we finished the race，I feel very cold，and I realized the cold feeling disappear when we did the race. That's so amazing. When I follow her，I only think how to follow her，how to defeat the race. After I finished all the race，I try to recall this memory，I feel very happy，and it also make me so warm. That experience let me know the importance of team working. I think I will bring it to the career of my sport. Try to spread it with my team and my athletes. Try to let everyone had own good memory. Let them warm.
