Lee picked up only one minor title during the 20 seasons. Discovered by Misbun Sidek, he was drafted into the national squad in 2000 when he was seventeen years old. After receiving his father's consent, Teh began to train Lee after school. He attracted the attention of local coach Teh Peng Huat, who asked Lee's father if he could take him as a student. Lee began to learn badminton at the age of 11, when his father, who liked to play the game, brought him to the badminton hall. In his early years, he favoured basketball, however his mother soon banned him from the game due to the searing heat of the outdoor basketball court. Lee was born in Bagan Serai, Perak, into a Malaysian Chinese family, to Lee Ah Chai and Khor Kim Choi. He retained his role, albeit serving it virtually. He was appointed as Malaysia's chef de mission for the 2020 Summer Olympics, but skipped the event due to his health concerns. On 13 June 2019, Lee announced his retirement after struggling to return to full fitness following a nose cancer diagnosis. He repeated the achievement twice more in 20, thus making him the most successful Malaysian Olympian in history. This achievement earned him the title Datuk, and led to then Malaysian Prime Minister Najib Razak describing him as national hero.

He won his first silver medal in 2008, also the first time a Malaysian had reached the finals in the men's singles event. Lee is a triple silver medalist at the Olympic Games, and the sixth Malaysian to win an Olympic medal. He is the fifth Malaysian player after Foo Kok Keong, Rashid Sidek, Roslin Hashim and Wong Choong Hann to achieve such a ranking (since official rankings were first kept in the 1980s), and is the only Malaysian shuttler who has held the number one ranking for more than a year. As a singles player, Lee was ranked first worldwide for 349 weeks, including a 199-week streak from 21 August 2008 to 14 June 2012. Datuk Lee Chong Wei DB, DCSM, PJN, DSPN, AMN, JP, PhD(SptsSc) (h.c.) ( Chinese: 李宗偉 Pe̍h-ōe-jī: Lí Chong-úi born 21 October 1982) is a Malaysian former badminton player.
