2018年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled as an "Internal Control Self-Evaluation Report" for the year 2018 by Beijing Snow Dragon Technology Co., Ltd. It contains detailed descriptions of the company's internal control environment, risk assessment, control activities, information systems, communication, and internal supervision. The report discusses the evaluation of internal control effectiveness as of December 31, 2018, and includes specific standards for identifying internal control deficiencies related to financial and non-financial reporting. The document is comprehensive, over 10,000 characters, and contains substantive content about internal control evaluation rather than just an announcement or certification. This matches the characteristics of an Audit Report / Information (AR), which includes standalone audit reports and internal control evaluation results, excluding full annual reports. It is not an Annual Report (10-K) because it focuses solely on internal control evaluation and does not present full financial statements or company activity overview. It is not a Regulatory Filing (RNS) because it is not a short announcement or certification. Therefore, the appropriate classification is AR with high confidence.

关于会计政策变更的公告
Regulatory Filings Classification · 95% confidence The document is an announcement from Beijing Xuedilong Technology Co., Ltd. regarding a change in accounting policies due to the adoption of new financial instrument accounting standards issued by the Ministry of Finance effective from January 1, 2019. It details the reasons for the change, the nature of the new standards, the impact on the company, and the approval by the board and independent directors. The document is relatively short (2449 characters) and serves as a formal announcement of the accounting policy change rather than a full financial report or audit report. It does not contain actual financial statements or detailed financial data but rather explains the policy change and its rationale. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for regulatory announcements that do not fit other specific categories.

内部控制规则落实自查表
Audit Report / Information Classification · 95% confidence The document is titled as an "内部控制规则落实自查表" which translates to "Internal Control Rules Implementation Self-Inspection Form." It contains detailed internal control checklists related to internal audit operations, information disclosure, insider trading controls, fundraising, related party transactions, external guarantees, major investments, and other important matters. The document is a self-assessment or internal control checklist rather than a financial report or announcement. It does not contain financial statements, earnings data, or regulatory filings such as audit reports or annual reports. It is also not a certification or a short announcement. The content focuses on internal control and compliance procedures, which aligns with internal audit or control information. Given the nature and content, this document best fits the category of Audit Report / Information (AR), which includes internal audit results and applied accounting principles, excluding full annual reports. The document length is under 5,000 characters but contains substantive internal control information, not just an announcement or certification, so it is not RPA or RNS.

关于举行2018年年度报告网上说明会的通知的公告
AGM Information Classification · 95% confidence The document is a notice about holding an online explanation meeting for the 2018 annual report. It states that the full 2018 annual report has already been disclosed on March 20, 2019, and the company will hold a web-based presentation on March 28, 2019, to help investors better understand the company's situation. The document does not contain the annual report itself or detailed financial data but is an announcement about an event related to the annual report. The document length is short (626 characters), consistent with an announcement rather than a full report. Therefore, this fits the category of AGM Information (AGM-R) as it relates to materials shared during an annual meeting or presentation about the annual report.

2018年度独立董事述职报告（朱天乐）
Board/Management Information Classification · 95% confidence The document is titled as the "2018年度独立董事述职报告" which translates to "2018 Annual Independent Director's Work Report." It details the independent director's attendance at board and shareholder meetings, opinions on various company matters including financial policies, related party transactions, internal controls, and other governance issues during the 2018 fiscal year. The content focuses on the independent director's duties, opinions, and oversight activities rather than presenting full financial statements or audit results. It is a detailed management-related report on governance and oversight rather than a full annual report or audit report. Therefore, it fits best under the category of Board/Management Information (MANG), which includes announcements or reports related to board members' activities and management oversight.

关于调整回购股份具体用途的公告
Transaction in Own Shares Classification · 95% confidence The document is a formal announcement by Beijing Xuedilong Technology Co., Ltd. regarding the adjustment of the specific purposes for its share repurchase program. It details the background of the repurchase plan, the changes in the intended use of the repurchased shares, the expected impact on shareholding structure, and includes opinions from independent directors and the supervisory board. The document references regulatory requirements from the Shenzhen Stock Exchange and company board resolutions. It does not contain financial statements or quarterly/yearly financial results but focuses on the company's share repurchase activities and related governance disclosures. Given the content and context, this document fits the category of a Transaction in Own Shares (POS) filing, which covers announcements about the company's buyback or sale of its own shares. The document length is under 5,000 characters, but it is a detailed announcement, not merely a notice of report publication or certification, so it is not RPA or RNS. Therefore, the appropriate classification is POS with high confidence.
