The soldiers at the checkpoint weren't very thorough in their inspections; there weren't many restrictions on what items people were allowed to bring in. There was no specific ban on flammable or explosive materials—their primary focus was verifying whether the individuals had the qualifications to enter Eastern Capital City. Without the proper qualifications, even if you carried nothing with you, you still couldn't enter. On the other hand, if you were qualified, you could enter carrying a mountain of gold, and no one would bat an eye.
Almost everyone who wanted to pass through the checkpoint was aware of this and cooperated fully. Upon reaching the inspection area, they would proactively present their identity cards or other items that could prove their identities.
