With the rise of DeepSeek, a mysterious “study guide” crafted by a team from Tsinghua University — “DeepSeek: From Beginner to Expert” — has also started to circulate online.
In fact, this material is a professional document written by Dr. Yu Menglong’s postdoctoral team from the New Media Research Center of the School of Journalism and Communication at Tsinghua University.
This 104-page manual not only details the various functions of DeepSeek but also hides the secrets of efficient learning for Tsinghua students. It serves not only as a reference book but also as a “survival guide” on how to coexist with AI.
1. What is DeepSeek? — When AI Becomes Your “Super Brain”
DeepSeek is a multimodal artificial intelligence system independently developed by a Chinese team, functioning like an “all-around assistant” with an infinite knowledge reserve, capable of helping humans complete complex tasks such as creation, analysis, and decision-making through natural language dialogue. Unlike ordinary tools, its core capabilities are reflected in:
1. Depth of Understanding Needs When you suddenly want to plan a trip to Yunnan late at night, just input “Help me write a Xiaohongshu-style travel diary for Yunnan, highlighting niche attractions and food,” and within 5 seconds, you can receive a complete guide that includes unique experiences like boating in the Puzhehei Wetland and the Jianshui Tofu Feast. This precise ability to capture users’ implicit needs stems from its profound understanding of the Chinese context.。
2. Breadth of Information Processing A hotpot restaurant owner can input “I am the owner of a hotpot restaurant in Guangzhou, I need to create 100 short video scripts to attract young people,” and DeepSeek will immediately generate creative content containing popular internet phrases like “How to cook tripe” and “90s health punk hotpot base,” completing in two days what would originally take three months.。
3. Intelligent Cross-Disciplinary Collaboration When a programmer is stuck debugging code, they can input “Help me optimize this Python web scraping code,” and it can simultaneously complete three tasks: correcting the code, improving performance, and suggesting solutions for exception handling, equivalent to having a technical team online 24/7.
2. The Triple Secrets Behind DeepSeek’s Popularity
Secret 1: Technological Breakthrough Reshaping Productivity
- Million-Level Token Processing Capability can analyze 300 pages of corporate annual reports at once, accurately extracting key financial indicators.
- Multimodal Interaction Revolution The Xi’an Cultural and Tourism Bureau used it to create the ancient poem “Shaanxi Travel,” maintaining the seven-character quatrain format while incorporating cultural symbols like the Big Wild Goose Pagoda and Yangrou Paomo.
- Miracle of Cost Control Under the same performance, the inference cost is only 1/10 of international competitors.
Secret 2: Accessible AI for All
- No Threshold Operation A 60-year-old owner of a Northeast restaurant used “Help me write a Spring Festival promotional poster in Northeast dialect style,” and received down-to-earth copy like “Unlimited sauerkraut and pork, super fragrant!”
- Comprehensive Scenario Coverage From students solving calculus problems, to fund managers analyzing listed companies’ financial reports, to housewives creating nutritious meal plans, forming an ecosystem of applications for all.
Secret 3: Safe and Trustworthy Localized Services
- Data Sovereignty Protection All computations are deployed on domestic servers, and government departments can directly use it for generating anti-fraud promotional content.
- Value Alignment When answering “The Meaning of Serving in the Military,” it can express positive energy by combining national sentiment and personal growth.

| Investment Analysis | Identifies potential stocks on the Sci-Tech Innovation Board | 70% Improvement in Information Coverage |
| Life Services | Customizes a 7-day self-driving itinerary for Yunnan | 95% Saving in Planning Time |
4. A User Guide for Ordinary People: Three Steps to Start an Intelligent Life
Step One: Precise Questioning Formula
“Identity Label + Scenario Demand + Style Requirements”:
- Basic Version“I am a college student and need to write a paper on ‘Ethics of Artificial Intelligence,’ which should include 3 typical cases.”
- Advanced Version“As a cross-border e-commerce entrepreneur in Shanghai, please use SWOT analysis to assess TikTok’s overseas warehouse layout, outputting a PPT outline with data charts.”
Step Two: Continuous Interaction Optimization
- Initial Draft Generation: “Write a promotional copy for a Valentine’s Day cake shop.”
- Refine Demand: “Add ‘pet-friendly’ elements and highlight low-sugar health points.”
- Style Adjustment: “Change it to a stand-up comedy style script.”
Step Three: Cross-Disciplinary Combination Innovation
- Cultural and Tourism Integration The Chengdu Cultural and Tourism Bureau combined hotpot culture with the history of Du Fu’s Thatched Cottage to produce a short video script titled “The Poetic and Spicy Assignment.”
- E-commerce Monetization Yiwu merchants used “DeepSeek + live broadcast scripts” to generate 500 product explanation scripts.
5. The Future is Here: Everyone is an AI Commander
The popularity of DeepSeek is no accident; it marks the official entry of humanity into the “intelligent collaboration” era. When a cultural and tourism editor in Shaanxi uses it to complete a monthly promotional plan in 3 hours, when a housewife relies on it to create a scientific parenting plan, when a retired teacher uses it to create and publish a poetry collection, we see not just technological innovation but the liberation of everyone’s creativity.
The most fascinating aspect of this era is: DeepSeek will not replace humans, but rather enable everyone to become the director of their own field — you are responsible for the wild creativity, and it is responsible for turning inspiration into reality. Now log in to the DeepSeek official website and start your journey of intelligent evolution!
Tsinghua University’s “DeepSeek User Manual” outshines all training courses with its zero-cost, high-efficiency approach. It is not only a “secret weapon” for Tsinghua students but also a shortcut for ordinary people to quickly master AI skills.
This 104-page manual not only records the usage methods of DeepSeek but also embodies Tsinghua students’ reflections on the AI era. It tells us that AI is not a tool to replace humans, but a partner to enhance efficiency. In Tsinghua Garden, DeepSeek has already become a powerful assistant for academic exploration, and this manual is the key to opening the door to learning in the AI era.
