Jiang Yang went to the cabinet in his room and pulled out two black color speakers like small devices. He switched them on, kept one device on the bedside table of his room, and walked out of his room carrying another device.
He went to Jiang Yuyan's room, knocked on the door lightly, and opened it upon not getting any response. The room was dimly lighted, but he could see his sister, who was asleep.
Stepping towards the bed with light footsteps, Jiang Yang kept the device on the bedside table and stepped out of the room as he closed the door.
As soon as the door of the room was closed, Jiang Yuyan opened her eyes, looked at the device that her brother left, and turned it off.
The next morning when Jiang Yang woke up, he saw his sister standing in the gallery near the railing. He came out of the room, and this time he made a sound of a door to let her know his presence.
