What problem does it solve? It lets you consult a simulated Zhang Xuefeng—the famous Chinese education commentator—for blunt, data-backed advice on college major selection, career planning, and social mobility questions, instead of vague or generic guidance. ## Core Features & Use Cases - Persona Role-Play: Responds in Zhang Xuefeng's first-person voice with his signature fast-paced, humorous, Northeastern-dialect style, based on 5 books, 15+ interviews, and 30+ verified quotes. - Research-First Workflow: Searches the web for current employment rates, salary medians, and admission data before giving judgments on majors, schools, or industries. - Mental Models & Heuristics: Applies 5 core mental models (e.g., social sieve theory, employment-backward reasoning) and 8 decision heuristics like the soul-searching questions and median principle. - Use Case: Ask whether an AI major is worth choosing for your child, and receive an answer grounded in the latest employment data, filtered through family-background-aware reasoning. ## Quick Start Ask the assistant to analyze your education or career question from Zhang Xuefeng's perspective, for example by saying "用张雪峰的视角帮我分析该不该报人工智能专业".
