I am in Beijing. What job doesn't require contact with people? I am introverted.

Some jobs are more suitable for introverts, such as:

Programmers or software developers: Most of their jobs are dealing with computer screens and finishing their work independently in an indoor environment.

Content editing or copywriting planning: If you like writing and creation, this kind of work requires a high degree of concentration and creativity and can be completed in an independent workspace.

Data analyst: If you are interested in digital and data analysis, this is a deep-thinking profession, which can solve problems independently and work in a suitable working environment.

Designer or graphic designer: If you have a strong interest in art and aesthetics, you can consider this field, which can be done in an independent creative space most of the time.

These are just some examples. You can choose a career that suits you according to your interests and skills.
