The 'carrying people across the river' problem is difficult for all 4 contestants of Road to Olympia

It was just a simple puzzle, but all 4 contestants in the show Road to Olympia had to give up because they couldn't find the answer.

In the Finish Line contest, contestant Huu Tri asked the following question: "A tourist group of 36 people crosses the river by boat. The boat can only carry a maximum of 6 people including the driver. Luckily, there is 1 person in the group who knows how to operate the boat. What is the minimum number of trips the group can take to cross the river?"

After thinking for a while, male student Huu Tri gave the answer 8 but it was incorrect. Immediately after that, another contestant pressed the bell to answer and gave the answer 6 trips. However, the answer was also incorrect.
