"Eh? Chen Xiao, are you here?"
"We're here. It's at the door." A boy tilted his head, holding his mobile phone on his shoulder and flipping through the contents of his black shoulder bag.
"Why don't you come in?"
"I haven't found the ticket yet," as soon as he finished speaking, a burst of joyful voice came from the phone, "I found it."
"I'll go find you later and hang up."
Li Xian smiled and said, "Bye."
