Tieu Vy faced off against 5 other candidates in the "Head-to-Head Challenge" round.

The Head to Head Challenge segment made a big impact at Miss World 2017, marking the first time it became one of the sub-competitions that contributed to the scores and determined the final top 40 placements.

Miss Tiểu Vy will face five strong contenders in the Head to Head Challenge.

This year, to give the audience a deeper insight into the contestants, the Miss World organizers have made a major change to the format: the head-to-head challenge will have two rounds, instead of just one as before.

This year, the 120 contestants will be divided into 20 groups, each consisting of 6 contestants, based on a draw. Miss Tiểu Vy is in Group 12 along with representatives from Egypt, South Sudan, the Bahamas, Montenegro, and India. This is considered one of the strongest groups among this year's contestants.

In Round 1, contestants will answer questions posed by the organizers. There will be one general question for the entire group and one individual question for each contestant. After the groups' videos are uploaded, viewers will have the right to vote for their favorite contestant through Miss World's social media channels, selecting the winner for each group. The 20 winning contestants will advance to Round 2.

In Round 2, contestants will present their philanthropic projects. Round 2 is relatively more intense, with contestants competing in a knockout format to secure a spot in the top 30 of the competition.
