reply:

During the reporting period, the amount of capitalized R & D investment was 160826 million yuan, accounting for 33.61% of R & D investment, an increase of 4.68 percentage points over the same period of last year, which was consistent with the increase of R & D investment in operating revenue.

During the reporting period, the company's R & D projects were mainly carried out at the level of its subsidiary Beijing Zhiyou Wangan Technology Co., Ltd. (hereinafter referred to as "Zhiyou Wangan") and its subsidiaries. During the reporting period, the company's R & D investment totaled 478452 million yuan, a year-on-year increase of 45.89%; The proportion of R & D investment in operating income was 16.56%, an increase of 4.87 percentage points over the same period of last year; With the increase of the company's R & D investment and the successful launch of some projects and reaching the sales state after passing the test, the capitalization amount of the company's R & D investment has also increased.

During the reporting period, the following three items of the subsidiary zhiyou.com security were transferred into intangible assets: mobile application security supervision and monitoring platform v2 0. Mobile application privacy compliance automatic detection platform v1 0. Hongmeng application reinforcement platform v1 0, totaling 160826 million yuan. In accordance with the relevant provisions of the accounting standards for Business Enterprises No. 6 - intangible assets on the capitalization of development expenditure, the company determines that the following conditions are met at the same time and makes corresponding accounting treatment: 1) it is technically feasible to complete the intangible assets so that they can be used or sold; 2) Having the intention to complete the intangible assets and use or sell them; 3) The ways in which intangible assets generate economic benefits, including being able to prove that there is a market for the products produced by using the intangible assets or the intangible assets themselves. If the intangible assets will be used internally, its usefulness shall be proved; 4) Have sufficient technical, financial and other resource support to complete the development of the intangible assets and have the ability to use or sell the intangible assets; 5) The expenditure attributable to the development stage of the intangible asset can be measured reliably. The company's accounting policy for the capitalization of R & D expenses is to divide the R & D internal R & D project expenditure into research stage expenditure and development stage expenditure. The expenditure in the research stage shall be included in the current profit and loss when it occurs. Expenditures in the development stage can only be capitalized if the above conditions are met at the same time. The company's research and development projects enter the development stage after meeting the above conditions and forming the project approval through technical feasibility and economic feasibility study. The capitalized expenditure in the development stage is listed as development expenditure on the balance sheet and transferred to intangible assets from the date when the project reaches its intended purpose. The above policies comply with the provisions on the capitalization of R & D expenses in the accounting standards for Business Enterprises No. 6 - intangible assets.

The company's R & D situation involves the R & D of basic technologies, customized development for specific key customers, exploratory development for new industry fields and the development of R & D capitalization projects. 1) For the R & D of basic technologies, including the R & D of software platforms and key components, the R & D results can not be sold separately, but need to be combined with the R & D investment in other aspects and finally complete the R & D work. Therefore, the research of basic technologies does not meet the conditions for entering the development stage and does not meet the provisions of the above standards. The company has not capitalized this type of R & D. 2) The characteristic of customized development for specific customers is that the purpose of R & D is not for the whole industry. Passing the test of specific customers means meeting the needs of specific customers. Therefore, the goal of R & D is to pass the test of specific customers. The development stage is short and accounts for a small proportion of the overall R & D. the company does not separate the research stage and development stage in R & D project management, which does not comply with the provisions of the above standards, Therefore, it is not capitalized. 3) In addition to the original business areas, the company is also actively expanding new industries. However, due to restrictions such as industry cognition and customer resources, there is great uncertainty about whether it can succeed in R & D, form mass sales and bring sufficient economic benefits to the company in the future. It does not meet the provisions of the above standards, and the company has not been capitalized.

As of the end of the reporting period, the company has 194 R & D personnel and has obtained 14 patent licenses and 88 software copyrights. The company has long been engaged in mobile network security business and deeply cultivated the mobile network security market. The company has carried out project research and development such as product upgrading for products with breakthrough in industry information and customer resources. Through the market and spatial capacity analysis and technical and economic feasibility analysis of various projects, the products developed are expected to realize mass external sales and bring sufficient economic benefits to the company. In terms of financial resources, the company has the ability to provide financial support for development through its own funds, bank loans and other ways. After the R & D project passes the test run and trial, it has the basic conditions to form a new product to a great extent, and the company has sufficient technical, financial and other resources to complete the development of the product through early technology accumulation. Therefore, after the research and development of such products pass the test and trial, they meet the relevant provisions of the accounting standards for Business Enterprises No. 6 - intangible assets.

During the reporting period, relevant internal and external evidences have been obtained for the three capitalization projects of the company. The internal evidences include the project initiation report, market analysis report, outline design specification, requirements specification, internal function and performance test report, deployment documents, user operation manual and released product list in the R & D process documents; External evidence includes third-party inspection reports, relevant software copyrights and software product certificates; In addition, the above three capitalized R & D projects have obtained or are applying for relevant software copyright and software product certificates during the reporting period, and multiple business contracts have occurred before or after December 31, 2021. The company believes that based on the above evidence, the above three R & D projects comply with the accounting policies of the company for the capitalization of R & D expenses, and the relevant accounting treatment complies with the relevant provisions of the accounting standards for business enterprises.

The company has provided the above-mentioned evidence materials to the annual audit accountant at the annual audit stage, but it still fails to provide evidence as required by the accountant. These evidences include the R & D project fund budget, man hour budget, man hour records of R & D personnel and other materials required by the accountant. The company's project plan has a clear allocation of R & D project personnel, but there is a lack of more relevant materials for recording and archiving. In the future, the company will improve the records and archiving of this link, increase man hour records and further improve process documents.

Item (2): the specific circumstances of the above seven companies involved in third-party payment collection, including but not limited to the time of registration, registered capital, legal representative, specific business cooperation with your company, whether there is an association or other relationship with your company, and the specific circumstances of third-party payment collection, including but not limited to the payment collection agreement, time, amount, proportion, customer name, business and specific accounting treatment, In combination with the above situation and the situation of Companies in the same industry, explain the reason and necessity of the third-party payment collection, whether it is commercially reasonable, whether there are additional conditions, whether it is in line with industry practices, whether there is a situation of fictitious income and payment collection by using external funds, and whether there are other third-party payment collection and account cancellation in the reporting period, if so, please explain in accordance with the above requirements.
