I'm not sure what "temu" you mean, because this word can have different meanings. If you can provide more context or information, I can better answer your question.

But generally speaking, to choose a good category, you need to consider the following factors:

1. Market demand: Choosing a category with sufficient market demand can increase your sales and profits.

2. Competition: If a category is already occupied by many people, you need to consider how to stand out in the fierce competition.

3. Personal interests and skills: Choosing a category that you are interested in and capable of doing well can improve your work efficiency and satisfaction.

4. Investment cost: Different categories may require different investment costs, including investment in manpower, material resources and financial resources.

In short, choosing a category that is easy to do requires comprehensive consideration of multiple factors. It is recommended that you make a reasonable choice based on your own situation and market demand.
