B2st's Yun Du Jun's graduation photos are the talk of the town.

On an online community's forum, Yun Du Jun's elementary, middle and high school graduation photos that were posted 2 years ago are once again attracting the attention of Netizens.

In the photo, Yun Du Jun's baby face is the total opposite of his current sharp image.

In the elementary school graduation photo, he looks like a model student wearing his glasses with his chubby cheeks and tidy hairstyle.

But, in his middle and high school photos, you can see a little of Yun Du Jun's current image without his glasses.

Netizens commented, "He was so cute when he was young", "He looks so different from now", "He got so good looking", "Did he get plastic surgery? Why does he look so different?" and etc.

Meanwhile, B2ST's new song which was introduced to the public on January 26 has been placed 1st on all online music charts.
