老当益壮,宁移白首之心;穷且益坚,不坠青云之志。· Age should make one stronger,and it should by no means change the mind of the white-haired. Misfortune should make one more steadfast and should not frustrate his lofty ambitions.
· A person in old age ought to keep up his ambitions; a person in poverty should not abandon his ideals.
(Wang Bo [c.650-676]: “Preface to the Prince of Teng's Pavilion”)
