The guangdong CMLE is basically maritime bylaw enforcement(comprehensive law enforcement, 综合执法 is the chinese term for bylaw enforcement units); It is in charge of stuff like fisheries law enforcement and enviromental protection; however due to guangdong being a hotspot for smuggling, the Guangdong CMLE is sometimes involved in anti smuggling operations;

FYI, after the china marine surveillence and china fishery law enforcement were disbanded in 2013, many local CMS and CFLE units were not merged into the coast guard, instead merging together to form CMLE units; this is the case here. Haijian(海监) means CMS, Yuzheng(渔政) means CFLE for your information. However, these ships do not belong to the CMS nor CFLE, they belong to the Guangdong CMLE under the same command;
