Su Xiaowan immediately said, "Let's start by checking the library to see if we can find her. We all know Zhang Ying's personality, I'm afraid she might do something desperate. We need to hurry up."
"OK."
"OK, let's go, let's go quickly."
...
Su Xiaowan and her friends had been searching every corner of the library, but there was no sign of Zhang Ying.
Everyone was sweaty and panting heavily from running around.
"Xiao Wan, I can't find her..."
"Xiao Wan, I didn't see her either."
"Xiao Wan, should we look someplace else, we have already turned this library upside down."
Su Xiaowan, also out of breath, said, "Alright, let's search the school. She hasn't many places to go anyway. Let's go. If we still can't find her soon, we should alert our advisor. I'm worried..."
Everyone agreed and they split up again. But as it approached sunset, the temperature dropped and they all began to feel the chill. If they stayed outside much longer, they reckoned, they might fall ill.
