Graduate creates perfect chemistry

Liu Huadong, 27, chose a different path from his classmates after graduating in chemistry from Qingdao Agricultural University in 2014.

Instead of appearing in the civil service exam or becoming a laboratory technician in a chemical plant like his peers, he rented a house in the rural area of Qingdao, East China's Shandong province, and established his own lab.

Over the past four years, he has extracted and collected all chemical elements except for some dangerous and radioactive ones.

Liu also runs a shop on China's biggest online shopping platform Taobao. He designs souvenirs with chemical elements and sells them, earning annual revenue of 200,000 yuan ($30,756).
