About "IT Hua Tuo"

Although technology is advanced today, I have found that many small and medium-sized enterprises (SMEs) are still very behind in their application of technology. The reason for this is that SMEs have limited resources, and there is very little information available in the market that specifically guides businesses on how to correctly use technological tools to support their operations from a business management perspective.

I’ve helped numerous businesses use technology to enhance operations. Now, I’m keen to share my long - standing IT and business management experience. My aim is to help SMEs grasp how to use technology for business growth.

“IT Hua Tuo” aims to use technology as a fundamental remedy to address the various operational challenges faced by small and medium-sized enterprises, allowing both bosses and employees to enjoy a better quality of life. Just like the ancient Chinese physician “Hua Tuo,” who possessed exceptional medical skills to help people.

Many people also know Hua Tuo in ancient China had outstanding medical skills and healed people. Similarly, I use IT know-how to assist others, and my Chinese name has the character “Hua”. So, I adopted “IT Hua Tuo” as my nickname for its simplicity and memorability.

My Journey


I grew up in a wooden house on Lion Rock in Hong Kong, living there until I was ten years old. Due to a typhoon, a landslide occurred near my home. As a result, the government needed to relocate us to ensure the safety of our family. From then on, our family had the opportunity to move into public housing.


In middle school, due to academic needs, my family bought me my first computer, which was equipped with an Intel 486 DX 33MHz processor. From that moment on, I developed a strong interest in IT and seized every opportunity to learn and practice. I read a lot of computer magazines and books, watched IT television programs, studied product manuals, and visited various exhibitions. To learn computer installation and repair skills, I even spent entire days at the computer store. When friends and family had computer problems, I would actively help out, working hard to solidify my IT knowledge. To learn and upgrade my computer, I saved money every month, putting all my savings into it. These efforts allowed me to consistently rank first in computer science during my high school years, and I was fortunate to represent my school in public competitions.


After graduating from high school, I directly entered the workforce. I originally wanted to find a job related to IT, but due to a lack of experience, I faced difficulties in my job search. In desperation, I first worked as an office assistant and used part of my salary to study more advanced IT knowledge in the evenings. After a year of hard work, I successfully landed a job at an IT company, starting a career in IT that lasted over 20 years.


Initially, I worked in computer technical support. Through hard work, I quickly advanced to the position of system engineer and senior programmer. During these years, I accumulated rich technical skills and practical experience, enabling me to independently complete various projects. Later, I joined a group company with operations covering mainland China and Hong Kong, serving as the head of the IT department, responsible for coordinating the IT system construction and the development and implementation of ERP software for the entire group. This experience not only allowed me to gain experience in large-scale system construction but also helped me master the basic knowledge of business management. During this time, I successfully introduced a software application that was little known in Hong Kong, which could be used simultaneously by nearly 500 users, saving the company nearly 500,000 yuan in licensing fees, and thus received the PCM Best Enterprise Solution Award. This honor influenced my approach to designing IT solutions in the future. I no longer blindly pursued large brand software but instead selected cost-effective products that met actual project needs, maximizing cost savings for clients and avoiding resource waste. This experience also motivated me to establish my own company, hoping to use my professional knowledge to help small and medium-sized enterprises develop better.


In the past, I have undertaken numerous representative IT projects, involving businesses of various sizes and multiple industries. The scope of these projects covers various fields such as system development, project management, and network and server construction. I have been deeply involved in everything from small system development to large enterprise-level systems and database integration, as well as from basic network architecture design to high-availability server clusters and cloud computing platform construction. These valuable experiences have enabled me to design comprehensive solutions from a strategic business perspective.


Technological development is advancing rapidly, and only by keeping up with the times can we achieve our best performance at work. Therefore, even when work is busy, I still participate in various training sessions after work to enhance my skills. At the same time, I also engage in various volunteer activities, hoping to contribute to society, help those in need, and make the world a better place.


My Projects Experience

SME Playbook


In the past, I could only provide services to customers individually for projects, and I was unable to share all my knowledge and practical experience with more people. Despite the advanced technology nowadays, many small and medium-sized enterprises (SMEs) are still quite behind in terms of technology application. There is very little information in the market that starts from the perspective of business operation and guides enterprises on how to correctly use technological tools to support their business operations. As a result, SMEs encounter many obstacles in their digital upgrading and transformation process. They may even suffer financial losses, miss out on development opportunities, and face increasing difficulties in their operations.​


Therefore, this drives me to make a determined effort to create the persona of "IT Hua Tuo," through which I can share various practical knowledge about IT, AI, and business skills with small and medium-sized enterprises (SMEs), and compile it into the "SME Handbook," so that more SMEs can receive assistance.



I’ll share the insights from Secrets for SMEs across various online platforms. My goal is to show you how to use technology to boost your business performance, achieve development objectives, and improve life for both business owners and employees. hope you’ll benefit from my content. Please like, bookmark, or follow me. You can also "buy me a coffee.", Your support keeps me motivated and enables me to share more valuable information.
