I am puzzled, why is the attitude of the tax bureau so bad?

The reason is that the power of government departments is too great, and the patriarchal thinking does not reflect the requirements of a service-oriented government. This is the result of thousands of years of official standard thinking. Change is by no means achieved overnight, and the overall quality of individuals is not high. This situation will be very common, especially at the grassroots level. In addition, there is no reasonable salary incentive mechanism for civil servants, and the low enthusiasm of staff is also one of the reasons. So don't affect your mood too much, just be happy.
