I was invited to participate in a meeting organized by the Oak Union in China in Tancheng, Shandong Province from 5th Nov to 7th November, 2018. From the invitation letter I learnt that the Oak Union in China is a non-profit organization established three years ago in Jizhou, Hebei Province (near Beijing) by a group of oak growers.
