  • The 2026 'Management Cadre Grand Classroom' series training at Xinlianxin Shenleng Energy is currently in full swing. The first and second sessions focused on two core themes—'Effective Communication' and 'Financial Thinking'—with senior leaders delivering the lectures. Nearly 70 participants, including department managers, heads, and key management personnel, attended, marking the full launch of the company's annual core management talent development program.

    The first session, hosted by Wang Wentang, was titled Effective Communication Empowers Business. Closely aligned with the company's strategic planning and annual operational objectives, the course centered on the core question of 'how communication truly serves clients and drives business.' It systematically covered the three pillars of communication, precise transmission mechanisms on the client and business sides, collaborative management across transportation, production, and quality control, technology and iron triangle empowerment, as well as communication mechanisms and collaborative culture. During the lecture, Wang Wentang used real business scenarios to analyze typical issues in transportation, production, and quality control in daily work, openly reviewed shortcomings, and proposed clear improvement pathways. He emphasized that effective communication is not a matter of attitude but a capability for business assurance, and its ultimate effect is reflected in rapid response to client needs and 100% satisfaction.

    The second session, hosted by Jing Baojun, was titled Building Financial Structured Thinking to Reshape Corporate Value. Starting from industry dynamics and the company's actual situation, he pointed out that traditional financial thinking tends to fall into a backward-looking accounting logic, whereas managers need to develop a systematic perspective of 'viewing the enterprise through finance and viewing the industry through the enterprise.' The course progressed through three levels—'Understanding Finance: Viewing Finance through Finance,' 'Applying Finance: Viewing Finance through the Enterprise,' and 'Strategic Finance: Viewing Finance through the Industry'—in a step‑by‑step and insightful manner. Using rich cases and clear logic, it guided participating managers to re‑understand the essence of finance: it is not merely accounting and compliance, but also the language of strategy, the map of operations, and the line of defense against risks.

    The 'Cadre Grand Classroom' is a series of capability-building platforms for the company's core management talent. Through executive-led, practice‑oriented course design, it aims to help managers transition from 'passive execution' to 'active creation,' truly enabling managers to possess business thinking, operators to have financial thinking, and strategists to form investment thinking. From communication empowerment to financial thinking, the two sessions are closely connected yet each with its own focus, jointly guiding management cadres to become a capable, responsible, and financially savvy backbone force in the journey of high‑quality development. In the future, the company will continue offering courses on strategic execution, team management, client service, financial thinking, and other topics, providing systematic and practical training to continuously supply core talent for the company's high‑quality development.
