Lin Huang thought the only clue he had now was the rubbish bin that disappeared.
"The third rubbish bin must have disappeared together with Lin Xin. If we find the rubbish bin, we should be able to find Lin Xin."
Lin Huang got the security personnel to contact their leader, Chen Wei.
"Mr. Lin, we've received the room number of the girl in ponytails. She’s staying in Room 321 on the ninth floor. I have contacted the girl’s father and got them to wait in their room. We can go over now." Chen Wei brought them this piece of news when he picked up the call.
"We can put that on hold first. I got another clue; a lady who managed a store around the area said there were three rubbish bins when it was around 5:40 p.m. but now, there are only two. The time the rubbish bin disappeared matched the time my sister went missing too. I’m suspecting the person who that rubbish bin also took my sister." Lin Huang presented his theory to Chen Wei.
