After Wen Yunfang left, Jiang Yao knew that her chance had come. The two servants were outside. She did not dare sneak into Wen Yunfang's room from the main door, so she climbed in from the balcony with her meager skills. Then, she put the train ticket to Tingzhou under Wen Yunfang's pillow.
When Jiang Yao returned to her room, the servant sent by Brother Ding pretended to clean Wen Yunfang's room and entered the room while the other servant was washing vegetables in the kitchen.
The servant lied when she said that she wanted to clean Wen Yunfang's room; she wanted to search for the room. After entering the door, she began to rummage through the drawers, dressing table, and then the bed. Naturally, she reached under the pillow. Then, she found the train ticket that Jiang Yao had put there.
