The person sitting in the hot seat of the special program "Who is a billionaire" broadcast on the evening of September 2, 2025 is Mr. Vu Ngoc Quynh - a university lecturer.
In the 7th question, he received a challenge: "Which Vietnamese female player has received the MVP title - outstanding athlete at the 2nd stage of the 2025 SEA V-League volleyball tournament?". The four responses were given by Nguyen Thi Bich Tuyen (A), Tran Thi Bich Thuy (B), Tran Thi Thanh Thuy (C) and Vi Thi Nhu Quynh (D).

As a sports lover, including women's volleyball, Mr. Ngoc Quynh was wondering between the two answers, Bich Tuyen and Thanh Thuy. These are also the two leading hitters of Vietnamese volleyball.
After using the 50-50 subsidy right, the two options Thanh Thuy and Bich Thuy were eliminated, leaving only Bich Tuyen and Nhu Quynh. Finally, the player chose answer A - Nguyen Thi Bich Tuyen. This precise choice helped him move on to the next question.

Previously, in the second stage of SEA V-League 2025, Bich Tuyen played impressively. In the final match against Thailand, the main striker of the Vietnamese team scored 45 points, achieving an attack efficiency of 55%, contributing greatly to helping the Vietnamese team overcome their opponents after 5 tense sets. Her brilliant performance helped Bich Tuyen win two individual titles, Best Opposite Setter and MVP.
Although he answered correctly the question related to sports, the journey of player Vu Ngoc Quynh on the hot seat stopped at question 8, when he answered inaccurately in the field related to literature.
