213. Yiyi and I are not stupid dogs.

The first few days of winter break, Xu Qingfan drew a rough sketch of the selfie stick based on his memory of the device, with the help of Zhang Yiyi and Lin Wanning for touch-ups and redrawing the draft, the task was deemed a great success.

After all, the technical design of the selfie stick wasn't complicated: a retractable stick, a phone holder, and finally a Bluetooth remote shutter button or a button on the bottom, and it was all set.

Xu Qingfan spent some time making a simple prototype of the selfie stick, with Lin Wanning and Zhang Yiyi standing behind the camera serving as Bluetooth photo-taking assistants, demonstrating his concept to Zhang Chunxue.

"Auntie, don't you think people look better when photographed from a high angle? Of course, your beauty is flawless from any angle, it doesn't really relate to the selfie stick, ha." Xu Qingfan removed the fixed phone, opened the recently taken photo, and showed it to her.
