Huang will now face his compatriot Yuqi Shi, the number 11 seed.

Shi was made to work for his final place against an unseeded opponent in fellow Chinese player Jun Peng Zhao, but he eventually came through 21-11, 15-21, 21-12.

In the women's singles competition, number one seed Busanan Ongbumrungpan of Thailand continued her impressive form to narrowly avoid a potentially embarrassing upset.
