I want to know the answer to the following question:
Similar tianguis might set up shop where?
All the background I'm provided with is that "Street vendors play their trade from stalls in the tianguis as well as at non-officially controlled concentrations around metro stations and hospitals; at plazas comerciales, where vendors of a certain "theme" (e.g. stationery) are housed; originally these were organized to accommodate vendors formerly selling on the street; or simply from improvised stalls on a city sidewalk.". Is that enough to answer the question?
Answer: yes
