Thanks for putting up the link. This really brings back memories.
I grew up in a family where my grandmother would make love letters, ji dan gao, and other goodies on CNY, on top of cooking for an extended, 4-generation family! Sadly, the knowledge and diligence passed away with her, and none of her SIX daughters, my aunts, ever learnt, or continued the tradition.
We live in a world now where increasingly, parents feel the need to shield their children from the rigours of everyday life and concentrate on school and work. I believe that, more than anything, has contributed to the fading of these traditions.
