This mountain climbing activity is led by the experienced Coach Wang, so everyone feels at ease.

Under the guide's leadership, the tourists visited the Forbidden City in an orderly manner.

Teacher Zhang led the team to participate in the math competition, and in the end the students won first prize.

During the company team building, Manager Li was in charge of leading the team, and led us to complete all the outward bound activities.
