好景不长 Did not last long ; Pleasant hours fly past ; The morning sun never lasts a day ; All Good Things

好景不常 The morning sun never lasts a day ; Good Things ; All Good Things ; Morning Glory

好景不常在 Every day is not Sunday

好景不长在 Every day is not Sunday ; Nothing Gold Can Stay

好景不长盛宴难再 every day is not sunday

在年景不好时 at a bad time of year

好光景不会长久存在 good times don't last long
