He was attending an exhibition of paintings from ancient China. He was so excited seeing Auspicious Cranes, a painting by Zhao Ji (1082-1135), or Emperor Huizong of the Northern Song Dynasty (960-1127), that he took a photograph of it and posted it on the spot. Soon, he was asked by a visitor from Tianjin if he was Dongmaiying from Sina Weibo.

"I recognized you because you are the most attentive visitor here," the visitor told Huang, who was surprised. More unexpected encounters swayed his decision not to post in real time again.

However, the visitor was right. Huang does have a keen eye for detail. Many of his pictures present details that most visitors would barely notice at a glance, nor would you find them highlighted on the exhibits' information cards.

His works do not necessarily show every exhibit in its entirety. Chunmeihuli, a user of zhihu.com, a question-and-answer website in China, thinks his work is more artistic, rather than from a purely observational perspective.

When it comes to those relics which involve patterns or figures of humans, Huang pays meticulous attention to the facial expressions, the body's sense of movement, the beauty of the body's curves and the smooth drapes on their garments, which largely represent the delicacy of the exhibits.
