but chinese wheelbarrows look a lot different form european ines

this can be directly derived from this

replace forward porter with wheel

a chinese wheelbarrow places the load in a compeltely different place - 
left and right of the wheel

this reduces the carrying force needed by the porter and allows a much 
larger wheel which is good for bad streets - but makes a completely 
differentv load distribution necessary
