Oddly enough, men at work signs in Taiwan feature the shape and colour choice of the U.S.A. type warning signs whereas most other signs are of the European kind.
Men at Work signs are wrongly suggesting that Taiwan is an island where people drive at the left side of the road (men work always looking away from the traffic, see Great Britain). The Children's Crossing Signs however, are from the right hand type (as expected).
Good point is that the digger is wearing an indigenous head-cap. From the many small differences between both samples, make sure that you notice the position of the spade relative to the heap.
Notice also the weird shape of the heap in the Taipei sign.
