A troop of monkeys executing what appeared to be a "military-style" formation, stopping vehicles in their tracks, seemingly demanding food in southern China.

The video was filmed in the city of Leshan in Sichuan Province on September 3.

According to a tourist named Mrs Tan, the first incident she witnessed was around 2:00 pm. She described seeing a red car, positioned in the opposite lane, being completely surrounded by the monkeys.

"These monkeys were strategically positioned all around the car as if they had planned their move," Mrs Tan explained. “While our car wasn’t encircled, we were halted by a monkey and had to reduce our speed. We proceeded only when the monkey in front decided to move.”

The monkey mischief didn’t end there. At around 5:00 pm, as Mrs Tan and her party were departing the scenic spot, they were met with a similar scene. This time, it was a white SUV, immobilised by the monkeys' coordinated efforts.

"We had to slowly manoeuvre our car through a small gap to get past," Tan elaborated. "As soon as I rolled down the window, one of the monkeys tried to intimidate me,” Tan recalled her visits to other scenic areas like Mount Emei, where she had seen many monkeys, but never before had she witnessed them exhibiting such tactical behaviour to halt tourists' vehicles.

Fortunately for her, her car was not detained, and she remains uncertain about how the white SUV eventually got free.

On September 4, a staff member from the Heizhugou scenic spot commented on the incident, stating that while the area is home to many monkeys, such orchestrated behaviour around tourists' vehicles isn't common.

He suggested that tourists feeding the monkeys might have prompted such actions. Following the events, staff members were dispatched to the scene to disperse the monkey troop.

The staff urges visitors not to feed the monkeys and to seek assistance from park personnel should they find themselves surrounded.

9月3日下午，四川乐山市峨边县黑竹沟景区内，谭女士驾车游玩时，看到几只猴子“排兵布阵”式围截车辆，讨要食物。

谭女士介绍，她进景区时是下午2时许，看到前方一辆红色的小汽车在对向车道上，被猴群团团围住。这些猴子分布在小汽车的前后左右多个点位，好像会布阵一样。“我们的车没被包围，但也被猴子拦住了，只好放慢车速，等蹲在前面的猴子挪动了，我们再开走。”
当天下午5时许，谭女士一行人驱车离开景区，在同一位置发现，前方一辆白色的SUV又遭猴群“布阵”围住，该车根本无法挪动。谭女士所在车辆只能从旁边的空隙慢慢开过去。“我一开车窗，猴子就吓唬我。”谭女士说，自己此前去过峨眉山等景区，也见过不少猴子，但第一次看到猴群还会“排兵布阵”，如此围截游客的车辆。幸运的是，她所乘车辆没被围截，她也不知道那辆白色SUV是如何脱困的。
9月4日，黑竹沟景区一名工作人员称，景区猴子虽多，但这样将游客车辆团团围住的情况不算很常见，有可能是一些游客停车喂食猴群引发。事发后，景区工作人员赶到现场对猴群进行了驱赶。该工作人员呼吁，游客不要喂食猴群，如遇到被猴群围住的情况，可向景区工作人员求助。
