Uncle Hao unfortunately fell unconscious while crossing the road, but fortunately a young man sent him to the hospital in time for treatment  After Uncle Hao was in stable condition, four strange boys, Chen an, Li Kang, Zhang Xin and Wang Fu, came to the hospital to see him  Uncle Hao asked them who brought him to the hospital, and their answer was as follows: Chen an: none of us brought you to the hospital  Li Kang: four of us have taken you to the hospital  Zhang Xing: at least one of Li Kang and Wang Fu did not send you to the hospital  Wang Fu: I'm not the one who sent you to the hospital
It was later confirmed that two of the above four people told the truth and two lied
It is Chen an and Zhang Xing who are telling the truth
