These signify welcome or good luck or something. Hang these in your house and say welcome to visitors. Or they give these to you when you arrive, sort of like a garland around your neck. My photo s in black n whote but these thingies are quite colourful.
Its quite interesting during these little visits. You learn so much. Whereever you are in asia, especially East Asia, we more or less share the same things. Food (with slight variations), clothinng, traditions etc.
I found we all use 'tekiding' or slight variations of them for carrying rice. Its all so interesting.
Im trying to organise a trip to Vietnam soon. Take a slow train ride from the North to the south.
