If I am summoned, can I go to the police station to collect the lost items?

Of course. According to the inquiry of relevant laws, summoning refers to the litigation activities in which the public security and judicial organs use summonses to inform the parties to criminal proceedings to be interrogated at a designated time and place. The summoned person may not have violated the law, as long as it is not illegal, he can go to the police station to collect the lost property. The police station is the grass-roots organization of the public security system and the agency of the higher public security organs.
