Filing Released Lang Actions
关于拟续聘会计师事务所的公告
Regulatory Filings Classification · 1% confidence The document is a formal announcement by Hanwei Technology Group regarding the proposed re-appointment (续聘) of its external auditor (an accounting firm) pending shareholder approval. It does not present any financial statements or audit results itself (so it is not an AR or 10-K/IR) nor is it a management or board personnel change. It is a regulatory announcement about auditor engagement that does not fit a more specific category, so it falls into the general Regulatory Filings (RNS) catch-all.

It is not a full quarterly or annual report, nor an earnings summary, management change, dividend notice, or other specific category. It is an ad hoc regulatory disclosure of an accounting event. Therefore it falls under the general ‘Regulatory Filings’ category (RNS).
