It should be good to make milk tea and juice in Huangguoshu central scenic spot, because Huangguoshu is very hot, and tourists usually feel tired and thirsty when they come out. At this time, a few dollars for a cup of milk tea or juice is very cool.

Tianxingqiao scenic spot can't work, because the guests who get off at Tianxingqiao will take the bus directly from the scenic spot, and they won't stay at all, and no one will buy it.

I work in Huangguoshu Health Supervision Office. As far as I know, so far, Huangguoshu has not been operated or is applying to operate Hong Kong eggs, milk tea juice and other foods.

I suggest you go to the field first, do a good job in market research and feasibility analysis, and avoid blind investment and unnecessary losses.

I hope it helps you.
