Not illegal. If the group purchase study package involves economic benefits, it will violate the Anti-Unfair Competition Law of People's Republic of China (PRC) and other laws and regulations. In addition, the Ministry of Education has issued the "Notice on Carrying out Special Remediation of Paid Make-up Classes in Primary and Secondary Schools and Teachers' Illegal Acceptance of Gifts and Gifts", which means that teachers are not allowed to accept any form of property from students or parents. Therefore, if the group purchase study package organized by the school involves economic benefits or other forms of value exchange, it will be regarded as illegal. However, it is legal to purchase learning materials only for teaching purposes, and there is no economic interest relationship with students or parents.
