Less than a month after joining the National Youth Team, Lin Dan was sent back to the Bayi Team due to a match loss. This painful lesson taught him that competitive sports are far more serious than he had imagined; one cannot afford to lose simply because of a bad day. From then on, he threw himself into training with intense dedication, striving to improve his professional skills, and managed to return to the National Youth Team in just three months.
In 2000, the National Team began selecting new talents. Due to his mischievous and stubborn nature, Lin Dan had left an impression of being difficult to manage on the coaches, so he was not included in the initial selection list. It was Director Gao Lujiang from the Bayi Team who used his connections to get Lin Dan into the National Team. Thus, Lin Dan, who was nearing the age limit, caught the last train and became a "latecomer" in the National Team.
When he first joined the National Team, Lin Dan was assigned to a dormitory converted from a basement. The space was dark, damp, and had poor signal coverage; he had to stand on the bed to send text messages, waiting until they were sent before sitting down. However, what bothered Lin Dan most was not the harsh living conditions, but the pervasive atmosphere of pressure. As a "latecomer" brought in through connections, he often heard gossip claiming he lacked ability and had only entered the team due to favoritism. Many of his teammates were already world champions, which made him feel deeply inferior. At the cafeteria, he dared not look up, always eating quickly with his head down and leaving as soon as he was done.
During his time in the basement, Lin Dan pushed himself under immense pressure, constantly increasing his training intensity to prove himself. He eventually won several championships, earning respect for himself and Director Gao. A year and a half later, Lin Dan finally moved out of the basement and into a dormitory upstairs.
林丹进入国青队不到一个月，便因比赛失利被退回八一队。这次惨痛的教训让他深刻意识到，竞技体育的严肃性远超想象，绝非因个人状态不佳便可随意输掉比赛。自此，他如饥似渴地投入训练，拼命打磨专业技能，仅用三个月便重新重返国青队。
2000年，国家队开展人才选拔。由于性格顽皮且倔强，林丹给教练留下了不服管教的印象，因此未能入选首批名单。最终，八一队高路江主任动用关系，将林丹推荐进了国家队。就这样，即将超龄的林丹搭上了末班车，成为国家队的“插班生”。
初入国家队时，林丹被安排住在由地下室改造的宿舍中。那里阴暗潮湿，且信号极差，发送短信时必须站在床上，待信号发送成功后才能坐下。然而，比起恶劣的居住条件，更让林丹难以忍受的是无处不在的压抑氛围。身为“关系户”，他常遭人议论，认为他能力不足，全凭背景进入国家队。加之队友中不乏世界冠军，巨大的落差让他极度自卑，在食堂用餐时不敢抬头，总是低头迅速吃完便离开。
在地下室居住的那段日子里，林丹顶着巨大的心理压力，不断加码训练强度，决心用实力证明自己。他最终斩获数个冠军，为自己和高主任争回了尊严。一年半后，林丹终于搬出地下室，住进了楼上的正式宿舍。
