Olympic and world champion Lin Dan ensured there would be no repeat of the women's stumble on Saturday by destroying fierce rival Taufik Hidayat 21-7, 21-14 in less than an hour.
Doubles pair Cai Yun and Fu Haifeng encountered more resistance against Markis Kido and Hendra Setiawan, but romped home in the third set to put China 2-0 up with a 25-23, 16-21, 21-12.
Chen Jin then made it a clean sweep by coming back from a game down to beat Simon Santoso 19-21, 21-17, 21-7.
"It was a perfect victory as those only appear in the textbook," China coach Li Yongbo told Xinhua news agency.
"There is a comment saying the 'Great Wall' was toppled in our loss of the Uber Cup, then today I would say we made it stand up again."
"Our team did not play well... although I had confidently predicted that we will retain the Cup," Li had said of the Uber Cup loss.
Lin, whose semifinal demolition of Malaysia's Lee Chong Wei paved the way for China's fourth consecutive title, was ecstatic with his return to form after a shock quarterfinal loss at the All-England Championships in March.
"It is the best performance I have had since the beginning of 2010," he said.
"I am very happy that such strong rivals as Lee Chong Wei and Taufik here inspired me to find my way back."
