Although many of us like to think we’ll always stay young at heart, no one can stop the inevitable march of time.

But one father and son have found a way immortalize their unbreakable bond – by posing for the same photograph for 28 years in a row.

These incredible pictures show how father Tian Jun, 56, and son Tian Li, 29, have changed over three decades since Li was born in 1986.

The final image in the series, taken this summer, is particularity special.
