Do black people have longer tibia, Asians have shorter tibia?

Edit Post

I'm not talking anything about racism. If it's true,then asian LLer need more on tibia and black LLer need more on femur

i find that black poeple have longer legs. i have been secret comparing alot of chinese and black and find that chinese has longer upper body while black has longer legs.  also i notice hand and foot size in black are bigger even though having same height

i find that tibia of black are same with femur while chinese people like me and my cousins have short tibia.    not sure

but a 180 cm black looks taller than a 180 cm chinese and i dont know why
