Chung sức

Chung sức (Together) is the Vietnamese version of Family Feud. It aired on HTV7 from January 6, 2004 until its cancellation on June 28, 2016, making it the second longest-running game show on HTV, tied with Đi tìm ẩn số (Find the Hidden Numbers/Finding the Unknown/Deal or No Deal), only behind Vượt lên chính mình (Surpass/Beyond Yourself/Overcome all Obstacles) a local game show. It is also the longest-running show ever produced by Dong Tay Promotion, an advertising company in Vietnam.

This is the first ever Goodson-Todman/Goodson show to ever be adapted to Vietnam while the second G-T/G show was Hãy chọn giá đúng (Choose the Right Price) based on The Price is Right while the third was Siêu Sao Đoán Chữ (Superstar Guess the Word) based on Match Game.

Game Format
Until 2014, the show began with the teams being introduced by an announcer. In the early episodes, team members were mostly employees for the same company. Later on, any contestant can form a team, and sometimes a team involved celebrities as well. From September 2013 until 2014, contestants were students from elementary and middle schools in Ho Chi Minh City.

Two teams of four (similar to the Australian version) play each game, each compete to win cash and prizes. The game consists of 5 questions, with the point values double in the fourth question and triple in the last. The team with higher score wins the game and move on to play Fast Money. In case of a tie, the scores are reset to zero and one more question will be played, with the points worth nothing extra.

From around 2007 to 2015, sometimes a question will have a Lucky Answer or Đáp Án May Mắn ("Good Luck") and a team member would receive 1,000,000đ (3,000,000đ voucher in 2015) for giving the Lucky Answer.

The teams will receive 10,000đ for a point scored in the main game (20,000đ in 2016).

The grand prize for the Fast Money round is 10,000,000đ (20,000,000đ in 2016).

Trivia
The logo was based on the 1999-2006 Louie Anderson/Richard Karn era. In 2015, Hari Won and Truong Giang were the first couple as hosts, they were then later replaced by Dai Nghia & Le Khanh in 2016. This is the second international version of Feud to have couples hosting the show instead of one single person. The first one of that nature was the short-lived Turkish version called Aile Boyu (Family Size) hosted by Cagla Sikel and Emre Altug for TRT1 from 2010 until 2011. The third version was the Lithuania version under the name Ant Liežuvio Galo (The Tip of the Tongue) airing on BTV since 2016, hosted by Radistai Jonas Nainys and Rolandas Mackevicius. In 2015, host Hari Won didn't emcee the first eight episode of the series.
