general comments can be included in part of business ethic.The main theme of doing this study is not to earn money, several constrains of the study mustbe included of course.

For example, it was not predicted that buyingHerbalife’s products relates to friend’s recommendation. Therefore, asking the reasons why theybuy the products (or other brands of products) is very important. However, the questionnaire didnot include this question. It increases the difficulty of analysis.In the further study, the hypothesis must be set carefully. Otherwise, fatal errors will be madeeasily.

Different group members can provide different opinions, so that the ideas of thestudy can be more objective.107
