I am a 20-year-old young man who wants to go to a big city to develop, but my sister is a lawyer. She told me that it was a waste of time to go to a big city without culture.

There is no simple answer to the question whether a big city with cultural background is necessary to develop. Here are some factors that may affect the problem:

Industry and occupation: Different industries and occupations have different requirements for cultural background. For example, working in the fields of culture, education and art may pay more attention to cultural background and knowledge reserve, while working in the fields of science and technology and commerce may pay more attention to practical ability and innovation ability.

Personal interests and specialties: Personal interests and specialties will also affect the requirements for cultural background. For example, if you like reading, writing, art and other fields, then you may pay more attention to cultural background and knowledge reserve. And if you like science and technology, innovation and other fields, then you may pay more attention to practical ability and innovation ability.

Job opportunities and competitive environment: The job opportunities and competitive environment in big cities are more intense, which means that you need to pay more attention to your own abilities and competitive advantages. If you have a good cultural background and knowledge reserve, then you may have a better competitive advantage in some fields.

To sum up, whether the development of going to a big city needs a cultural background depends on the influence of many factors. If you have a good cultural background and knowledge reserve, then you may have a better competitive advantage in some fields. However, don't worry too much if you lack cultural background and knowledge reserve. You can improve your ability and competitive advantage through self-study, practice and training. Most importantly, you need to know your interests and specialties, and choose the industry and occupation that suits you.
