Hundreds of books, ranging from English picture storybooks to history-related ones, line the wooden shelves on one wall.
There are also kid-size boxing gloves and badminton rackets.
Colourful motifs of flowers and Chinese words for knowledge, wisdom and talent liven up the white walls.
But this is not a typical classroom in a typical school.
Instead, it is an apartment that has been turned into an informal school for children whose parents have pulled them out of China's education system to have them homeschooled.
Located in the northern Changping district of the Chinese capital, Beijing's Dragon Academy - or Long Xueyuan - was set up last year by homeschooling champion Zhang Qiaofeng, 48.
The former head of a medical research firm quit his job two years ago to homeschool his son Hongwu, after finding traditional schools unhealthy for a child's development as they were too rigid and exam-oriented.
"The effectiveness of such a teaching method is higher because it's just one to one or just one to a few. It is also targeted to the specific needs of a child," he said of his homeschooling method.
