Generally speaking, the reimbursement standards for travel expenses include transportation, accommodation and exchange activities. The specific standards may vary according to different regions and units, and will also be adjusted according to different travel purposes and itineraries.
I suggest you consult a specific unit or local financial department to find out the travel expense reimbursement standards of local units or units. They will give specific standards and regulations according to relevant policies. If you work in Binzhou, you can consult Binzhou municipal government or relevant departments in Binzhou to understand the specific reimbursement standards for travel expenses.
