Heavy snow hit east of Jilin Province a few days ago, leaving an accumulation of 5 centimeters of snow on the ground. The icy roads made customs control and inspection at the port difficult. To reduce the adverse impact brought by the bad weather, officers of Changbai Customs House (affiliated to Changchun Customs District) adopted countermeasures based on a contingency plan to ensure quality customs control and services would be in place.
