Actively take measures to reduce the use of paper in terms of technology and systems. In 2019, we continued to promote the electronic
management of accounting files, electronic ordinary VAT invoices, electronic bills and paperless business, and comprehensively promoted
the electronic reimbursement of electronic invoices and the automation of tax declaration. The promotion of VAT electronic ordinary invoices
was praised by the State Administration of Taxation, and won the second-class achievement award of the 15th Enterprise Management
Modernization Innovation in the communications industry. The practice of electronic invoice reimbursement, recording and archiving is
the first batch of pilot units in the country to promote electronic invoices and electronic archives, and successfully passed the acceptance
inspections by the National Archives, Ministry of Finance, State Administration of Taxation and other relevant ministries and commissions.

【Issuance of E-Invoice on Mobile Phone】
With the support of the Municipal Taxation Bureau, the Zaozhuang Branch of Shandong Province implemented the task of "issuing electronic invoices
by mobile phones for agents" in 2019. Through the establishment of a commission and invoice push system for agents, the collection of tax information,
the verification of tax invoices, tax declaration, as well as reimbursement and payment have been connected, and agents have changed from issuing paper
invoices to the tax authorities to directly issuing electronic invoices through registered mobile phones, which not only achieves paperlessness, but also
improves efficiency.

Using the commission and invoice push system eliminates the need to go to the tax bureau and telecommunications companies to submit invoices back and forth, and
I feel the convenience brought by informatization.
