G share
G股

G shares (Chinese: G股) refers to shares traded in the stock exchanges of mainland China that belong to companies that have accomplished stock right division reforms, and have regained business on the market. Owing to the provisional designation of the letter "G" for such stocks during testing of a proposed bill, the category of industries were referred to as the "G board", and the shares as "G shares".
G股（英文：G Shares) 是指在中国大陆证券交易所交易的股票，属于已完成股权分置改革并已恢复市场业务的公司。由于在对拟议法案进行测试期间，此类股票临时指定了字母“G”，因此行业类别被称为“G板”，而股票被称为G股。

H share
H股

H shares (Chinese: H股) refer to the shares of companies incorporated in mainland China that are traded on the Hong Kong Stock Exchange. Many companies float their shares simultaneously on the Hong Kong market and one of the two mainland Chinese stock exchanges in Shanghai or Shenzhen, they are known as A+H companies.

H shares are also held by a nominee service company "HKSCC Nominees Limited", which was owned by Hong Kong Exchanges and Clearing.
H股也由提名服务公司“HKSCC Nominees Limited”持有，该公司为香港交易所和结算所所有。

Price discrepancies between the H shares and the A share counterparts of the same company are not uncommon. A shares generally trade at a premium to H shares as the People's Republic of China government restricts mainland Chinese people from investing abroad and foreigners from investing in the A-share markets in mainland China.
同一家公司的H股和A股之间的价格差异并不罕见。由于中华人民共和国政府限制中国内地人在海外投资，以及外国人在中国内地A股市场投资，A股通常比H股溢价。
