How can I mark diodes and LEDs on PCB to avoid confusion of Chinese PCB fab?

(On every board we submit a design for assembly, some designers may make PCB fab confused about the orientation of diodes or LEDs. And we had both Eagle's default diodes and KiCad's default diodes sent back from Chinese fab.)

I guess, we may add a silkscreen “+” and “-” just outside of the footprint on either end.  Just put the diode schematic symbol on the silkscreen. Very Clear.

What Others Are Asking

What is an average CPH speed for hand SMD assembly?

What would be the average speed of assembling surface mount components on to a PCB for an experienced person? Assuming they have desk that is correctly set up (pick and place station) and the PCB has solder paste already applied.
