There are many ways to increase your personal income from a side job.

Here are some common ways:

1. Start a business or self-employment: If you have a specialty or skill, you can consider starting your own small business. This can be to provide services (such as teaching music, art, teaching, etc.) or to sell products you make (such as handicrafts, homemade food, etc.).

2. Online sales: Use e-commerce platforms such as eBay, Amazon and Taobao to sell your own products (such as second-hand items, handicrafts, etc.), or use your skills to provide online services (such as writing, design, translation, etc.).

3. Sharing economy platforms: Join sharing economy platforms such as Airbnb, Uber or Didi Chuxing to rent out your house, vehicle or other resources to earn extra income.

4. Online education: Use the Internet to conduct online education, guidance or tutoring with students. You can teach subjects you are good at or provide services such as language teaching.

5. Sideline job: Look for part-time job opportunities, such as weekend or evening jobs. You can consider industries such as educational institutions, retail stores, restaurants or customer service centers.

6. Take advantage of your hobbies: Turn your hobbies into side jobs, such as photography, painting, writing, music performance, etc., and earn extra income through exhibitions, publishing, performances, etc.

No matter which side job you choose, you need to consider your own skills, interests and time investment. When executing a side job, make sure to operate legally and comply with tax and related laws and regulations. In addition, keep a balance with your main job and ensure that the side job does not interfere too much with your main job.
