1, a city court has jurisdiction; Reason: The defendant sued by Silian Company is Changyun Company, and the object of the lawsuit is the transportation contract relationship; As the destination of transportation contracts, cities have jurisdiction over disputes over transportation contracts;

2. The court's litigation status of Sambo Company is correct, but the identification of Elda Company is wrong; Reason: Sanbao Company has no independent claim to the litigation object in the dispute of transportation contract. It has delivered the goods in the color TV sales contract with Silian Company, and intercepting the color TV halfway infringes upon the legitimate rights and interests of Silian Company. As a creditor of Sanbao Company, Erda Company has an independent contractual relationship with Sanbao Company, and its independent claim can only be directed against Sanbao Company, but not against Silian Company. After the payment is completed, the ownership belongs to the in-transit color TV of Silian Company.
