In 2013, Tsai Ming-Liang was invited by Malaysian filmmaker Tan Chui Mui to make a short film for an anthology film, "Letters from the South". Tsai Ming-Liang returned to his hometown in Kuching, Malaysia and made a "Walker" film at his childhood home, "Walking on Water". The seven-storey flat which contained the happy memories of his childhood is now occupied by strangers. His old neighbour, an older girl who used to bathe and feed him when he was a child, has also grown old.
