This tech whizz in southern China used several calculators to play a Taylor Swift song.

Impressive video filmed in the city of Dongguan in Guangdong Province on October 6 shows a 21-year-old boy named Liu Haoming using three calculators to play Taylor Swift's "Love Story" and four calculators to play S.H.E's "Ring Ring Ring."

Liu had to become familiar with the songs and with the tone of each button on the calculators. It only took him a few minutes to be able to play the songs on the devices.

According to reports, Liu majored in computer science and minored in music at university.

The 21-year-old grew inspiration from someone using a single calculator to play music. Liu went one better and used several to make music.

Liu can use up to six calculators to play a section of the music in a game called "Genshin Impact."

近日，四川成都。00后小伙用计算器弹奏音乐，动听悦耳令人赞叹。当事人刘同学表示，他大学主修的是计算机，辅修音乐。之前看到有人用一个计算器演奏音乐，他觉得有些单调，便尝试着用多个计算器合奏。首先需要把曲子熟悉两遍，然后熟悉每个按键对应的音调，结果几分钟就能弹出来，感觉也没有太难。
