It's approaching, when? On the 28th Sept. Over here we just eat (well, I don't really) mooncake. The Mid-Autumn Festival is not as big here as Far East. There's festivals going on in Hong Kong.
I remember when I was younger, my mom bought me some lanterns (battery-operated ones), not sure was it from London Chinatown or from Hong Kong. Hmm, but just read this on the HK gov site about dangerous toy lanterns warning.
But year in year out, not much else goes on here in Ireland.
