Raw bird's nest?

Hi! My aunt (Chinese nationality) and her 2 children are on holiday in Indonesia now..
She plans to bring back half a kilo of raw bird's nest back home for personal consumption (the dried one in cup shape)..
Is it allowed, since above i read "edible bird's nest" (is that means the ready to eat one?) is prohibited to go into China?
And how the custom taxes will be applied? How much a person allowed a duty free allowance?
Thanks a lot in advance!
