However, Manush Shah and Jeet Chandra exited after losing their main draw matches in the first round itself.
Before taking on the Taiwan opponent, the second-seeded Manav defeated Canada's Jeremy Hazin 11-9, 11-6, 11-3, 11-5 to earn a meeting with Feng, who was equally adept to the demands of the round of 16 ties when he took on the Indian.
Despite the Indian taking the first game for a psychological advantage, Feng came back strongly in the second to level the score.
The match, tantalisingly poised, went the same way until the fourth game. But the tie took a definite turn when Manav managed to win the fifth game after four deuces and saving two game points.
From there, it was Manav all the way as his Taiwan opponent seemed to have thrown in the towel after the crucial loss in the fifth game.
The Indian takes on China's Xiang Peng in the quarters.
And, if he gets past the Chinese hurdle, the Indian will meet the winner between Japan's Yukiya Uda and China's Xu Yingbin in the semi-finals.
The sixth seed Indian pair will take on Taiwan's Feng Yi-Hsin and Li Hsin-Yang in the quarters.
