The director of the Anti-drug Bureau of the Ministry of Public Security is a leading cadre at the official level, and the director of the Provincial Public Security Department is also a leading cadre at the official level. However, some provinces, cities and districts have directors of public security departments, such as deputy governors and directors of public security departments. In this case, the director of the public security department is actually a deputy ministerial-level leading cadre. So which level is high, the key is to see whether the director of the provincial public security department belongs to the high match. If the public security bureau chief belongs to a higher rank, the rank of the public security bureau chief is higher than that of the narcotics bureau chief of the Ministry of Public Security. If it is not a high rank, it is a flat rank.
