Shanghai Jiaotong University (SJTU) is an excellent institution in the field of information security in China, why don't more people recommend SJTU? Here are some possible reasons.

Relatively low visibility: Compared to other well-known colleges and universities, SJMIE is probably relatively low in visibility. This may be due to the fact that the college has been established for a relatively short period of time and has not yet built up a high level of visibility and reputation. As a result, many people may not know much about SJMC and would not be able to recommend it to others.

Specialized disciplines: SJMC focuses on research and education in the field of information security, which makes its disciplines relatively specialized. Compared to some comprehensive universities, SJMC has a relatively small range of specialties, which may not suit everyone's needs. Therefore, even if some people are aware of SJMC, they may only recommend it to those who are interested in the field of information security.

Relatively small enrollment: SJMC's enrollment is relatively small, with a limited number of admissions each year. This also makes the college's enrollment relatively competitive, which may result in some interested people not being successfully admitted. As a result, even if someone recommends SJMC, they may not be able to get into the college due to enrollment restrictions.

Inadequate publicity and promotion: The publicity and promotion of SJMC may have been relatively inadequate to adequately communicate the strengths and features of the college to a wider audience. This may result in fewer people knowing about SJMC and being unable to recommend it to others. If the College can strengthen its publicity and promotion work, it will help to increase the visibility and influence of the College.

It is worth noting that SJMC continues to be recommended and chosen by many as an excellent institution. While it may not be widely recommended, this does not mean that VSCCI is not worth considering. For those interested in the field of information security, SJMI offers a top-notch educational and research environment that has produced many outstanding individuals. Ultimately, whether or not to choose SJMI depends on one's knowledge of the institute and their needs.
