Dear parents:

On behalf of the Family Committee, I would like to announce the details of the bill revenue and expenditure of this activity. We strictly abide by the principle of openness and transparency, and make a detailed record and arrangement of all revenues and expenditures.

In this activity, we earned XX yuan, of which XX yuan came from the voluntary donation of parents and XX yuan came from the sponsorship of sponsors. We spent a total of XX yuan, including XX yuan for material procurement, XX yuan for labor service and XX yuan for venue lease.

We have recorded and sorted out all the income and expenditure in detail to ensure that every income and expenditure is well documented. At the same time, parents are also welcome to supervise and inspect our work.

Thank you!
