Hangu is a name that appears on more than one map, so the first thing to settle is which Hangu you are travelling to.
This guide is for the traveller who already has a reason to be in Hangu and wants to know what can be done with the time, rather than for someone choosing a holiday destination from scratch. It covers the one named place in the sources, and it says plainly where the sources stop.
1. The 'sun gate' mall
It also has a beauty parlour, so a visit can cover both shopping and personal care in the same stop.
Treat it as an errand stop rather than a sight: go when you need jewellery, supplies or the beauty parlour, and combine it with whatever else has brought you to Hangu that day. The sources give no opening hours, so check locally before setting out.
If you only have one day
Afternoon: Visit the 'sun gate' mall for jewellery, other supplies, or the beauty parlour.
