Top seed Lee Chongwei beat German Bjoern Joppien in straight sets in the second round on Wednesday to move one step closer to a possible encounter with seventh seed Chinese Bao Chunlai in the quarterfinals of the World Badminton Championships.
The second seed Lin Dan of China also found no trouble in disposing of Canadian Bobby Milroy 21-16, 21-17, a deceptive scoreline as the 22-year-old Lin intentionally played a longer match so that he could have more time to get used to the court.

The 23-year-old Lee shook off a slow start to win by 21-18, 21-14 in 27 minutes.
"My form is not so good right now, I need to do more work," he said.
When talking about the possible meeting with Bao, he said :"There is no easy games in the World Championships, every game will be tough, as the newly introduced 21-point scoring system makes the games treacherous."
"For sure, the Chinese players will be my toughest rivals in this championships," he added.
Bao advanced to the third round after beat Juergen Koch of Austria 21-13, 21-14.

The 31-year-old reigning Olympic titlist manifested a strong desire to play.
"Finally I can play the match now, I have been working out for five days, I am afraid too much training will wear away my forms," she said.
