On August 27, 2014, Attorney Jin Bingyi, Managing Partner of Runyi Law Firm, was invited to provide legal training for Pufa Machinery, with the lecture topic being "Letter of Credit Financing in Import Agency Business and Legal Risks in Export Agency Business."

With the rapid development of China's foreign trade economy, foreign merchants have continuously entered the Chinese market, and import and export agency businesses have been increasingly applied in international trade practices, becoming one of the commonly adopted trade methods. By virtue of its security and independence, letters of credit have long held a dominant position in international trade. However, due to legal and procedural deficiencies, various risks exist in import and export agency businesses. Combining Pufa's self-operated import and export agency business, Attorney Jin explained the risks and challenges of import and export agency businesses in a simple and profound manner, encompassing both theoretical and practical aspects. He also proposed targeted strategies and recommendations for the enterprise, which were highly praised by the attending leaders and colleagues.
