Long Term Vegetarian In China

I met a local vegetarian woman in China a few days ago who told me she has never eaten meat in her life. She looked healthy, fit and happy. I didn't ask her what her age was, but my guess is mid forties. Since Chinese people generally don't eat dairy or drink milk, I asked her how she gets her B12. She said she eats two eggs every morning for breakfast and that's it. It was definitely inspiring to meet a healthy, long term vegetarian in China!
