Learn technology? Which is better?

The answer is for reference only, 1, and there is a demand for job application according to age and location. Also consider the cost of learning. 2, according to my cousin's personal hobbies, such as personal expertise, or according to my cousin's personality temperament, choose the type of work he can adhere to for a long time. 3. For example, boys can learn a lot, such as the development and after-sales of mobile phones, computers, automotive electronic products, gourmet beauty salons and nail art, as well as things that are closely related to people's lives, such as baking, coffee pulling, food and clothing, such as logistics express delivery, for example, some people do online shopping, and some people do fitness coaches (famous people can also be professional coaches for stars). Some people are cooks in star-rated hotels, so they should study hard. In the future, they can study R&D while working and take exams to become world-class chefs. It is also said that the Blue Ribbon Chef School in Shanghai and Guangzhou is also good (just heard that there is no advertisement). Everyone can find a job, and as long as they are willing to suffer, they will have a future. For reference only, I wish you a bright future and good luck.
