Quercus fabri

Quercus fabrei, or Faber's oak, is a species of deciduous oak tree found in China mainland (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Henan, Hubei, Hunan, Jiangsu, Jiangxi, southern Shaanxi, Sichuan, Yunnan and Zhejiang provinces) as well as Hong Kong (Tai Po and North districts). Faber's oak can take on the form of either a large shrub or a tree, with the latter form reaching up to 20 metres in height. The tree has elongated leaves, with the tip of the leaf being wider than the base. The leaves are serrated, although the teeth are smaller than those of more well-known oak species such as Quercus robur....read more on Wikipedia.
