In the Lesser Hinggan Mountains, innumerable white birch trees, intermingled with Korean pine and sawtooth oak, create a scene that reminds Xu Jing, 64, of a great green ocean.
She still remembers how birches were described in an essay she learned long ago in primary school.
Based on her deep sentimental attachment to the trees, Xu founded Tiandiyuan Biotechnology in Yichun, Heilongjiang province, in 2014. Its main focus is harvesting white birch sap.
