The funny things is, most malls in China, the retail clothing stores are also doing poorly!! They are also having tough time.
Mainland China economy is pretty bad too. People are generally spending a lot less or buy online. Secondly, people here generally are less loyal and flock to places that is the lower price (I am the same )
Even mall like IFS, only the food court or kids play around is jam packed with people.
Side note: I was in HK last week, did the mall turn down the AC a bit to save on utility bill? In previous year, the AC in malls are freezing cold! This year, I thought is less so (actually more comfy).
