"孫公司指的是子公司的子公司，sub作為前綴有在……下面、下位的意思，所以可以用sub-subsidiary 這個詞來表達。如：

證券公司應當將所有子公司以及比照子公司管理的各類孫公司納入全面風險管理體系， 強化分支機構風險管理，實現(xiàn)風險管理全覆蓋。全面風險管理體系應當包括可操作的管理制度、健全的組織架構、可靠的信息技術系統(tǒng)、量化的風險指標體系、專業(yè)的人才隊伍、有效的風險應對機制。

A securities company shall include all its subsidiaries and sub-subsidiaries managed as subsidiaries in the all-round risk management system to enhance the risk management in branches and realize the full coverage of risk management. An all-round risk management system shall cover operable management rules, a sound organizational structure, a reliable information technology system, a quantitative risk index system, a professional talent team and an effective risk response mechanism."
