As a crucial channel for soliciting taxpayers' demands, appeals, opinions, and suggestions, it assists tax authorities in meticulously analyzing public tax-related messages. Messages of reference value to tax-related work are selectively incorporated, and tax-related issues raised by the public receive timely responses and resolutions.
