At which port do Gansu's goods exported to the EU usually board the ship?

Bulk cargo, including containers and liquid bulk cargo (crude oil, refined oil, chemicals, liquefied natural gas/liquefied petroleum gas, etc.). ), ro-ro ships, and cargo ships transporting timber and logs are mainly loaded in Tianjin Port, while bulk commodities such as coal, ore and rare earth are mainly loaded in Qinhuangdao Jingtang Port and Cangzhou Huanghua Port, and bulk goods including large-scale projects and industrial equipment are mainly loaded in Lianyungang. Tianjin Port is preferred if necessary!
