This project was originated from my encounter with a poem written by Zhang Heng 张衡, a celebrated astronomer, mathematician and geographer of Han Dynasty, who invented the world's first seismoscope as early as 132 AD. And yet contrary to the groundbreaking advancements Zhang Heng achieved as a scientist, in this poem titled Four Worries 四愁诗, he was perpetually torn in between his longing for the remote lover (or remoteness itself) and his melancholic hesitations, between the imagination of a great journey and the seemingly inescapable stillness.
