At customs supervision places implementing the dual-channel system, 1. The passengers who carry the articles required to declare should choose the "Things-to-Declare Channel" (also known as the "Red Channel"); 2. The passengers who do not know the customs regulations or how to choose the channels should choose the "Things-to-Declare" Channel to make declaration; 3. Other passengers except those who shall declare as specified may choose the "Nothing-to-Declare Channel" for their entry or exit.
