In business contexts, choho might be used to refer to a valuable employee, a helpful tool, or important information that significantly benefits the organization.

The term 付随 (fuzui) translates to "incidental" or "associated." In business and accounting contexts, it often refers to costs or activities that are supplementary or arise as a result of primary operations.

Another context where fuzui is used is in the categorization of expenses for training and seminars. Costs that are incidental to training, such as travel and lodging expenses for attending a seminar, can be categorized under training expenses if they directly relate to the training activities.
