Spro 公司发电机使用费用评估 - 额外增加 CNY 4000

Due to Spro Company's insistence that generators were used on the 17th and 18th, and electrically driven equipment was used during the actual cleaning process on these two days, it is recommended to accept the generator usage fees for these two days. Based on our assessment, the daily cost is approximately CNY 2000, so this expense will be increased by CNY 4000 on the original assessment basis.
