I still prefer the Dong Yuhui from back then on the podium.

Back then, he had a mushroom haircut and acne on his face,
During breaks, he would play with his phone and joke around with students. He was so happy!
Forced by capital, he has become like this now, being pressured to sell Spring Festival couplets in live streams, earning the livelihood of ordinary people’s small businesses. The common people are finding it even harder.
Maybe Teacher Dong is really more suited to standing on the podium, rather than wearing a serious face and apologizing, exhausted physically and mentally to sell products.
Dong Yuhui probably doesn’t want this either, being questioned why he’s抢小商贩生意 (stealing small vendors’ business) when selling Spring Festival couplets. He can’t control that either!
