Instances of musical instruments (Q34379) are typically individual specimens and shouldn't be subclasses. If you're working with a proper subclass, try setting P31 = "type of musical instrument" (Q110295396) (English)
乐器（Q34379）的实例通常是单个乐器，不应将其设置为子类。如果您确实需要使用子类，请尝试将 P31 设置为“乐器类型”（Q110295396）。 (Chinese)

Often causes works of art to be conflated with the practice or study of art. Classes of artworks should be subclasses (directly or indirectly) of "work of art" (Q838948). Most exceptions should be the subject of separate none-of constraints. (English)
这常常导致艺术作品与艺术实践或艺术研究混淆不清。艺术作品类别应该是“艺术作品”（Q838948）的子类（直接或间接）。大多数例外情况应通过单独的“非此项”约束来处理。 (Chinese)

humans are generally not modelled via subclasses, often roles that humans can have are mistakenly defined as subclasses of a human; if unavoidable, instantiate occupation, role, or class of human instead. (English)
людзей звычайна не мадэлююць праз падклясы; часта ролі, якія могуць мець людзі, памылкова вызначаюць падклясамі чалавека (Belarusian (Taraškievica orthography))
人类通常不通过子类进行建模，人们常犯的错误是将人类可以扮演的角色定义为人类的子类；如果无法避免，则应实例化人类的职业、角色或类别。 (Chinese)

大多数以这种方式识别出来的项目实际上都是职业（P31）的实例。将“面包师”这样的职业定义为职业的子类，就意味着（荒谬地）所有面包师都是职业 (Chinese)

Industrial sector (Q8148) is not a class, but a particular sector of the economy. Individual industries should be instance of (P31) industry (Q268592) instead, and may be part of (P361) the industrial sector (Q8148) if they involve manufacturing. (English)
工业部门（Q8148）并非一个类，而是经济的一个特定部门。各个具体行业应该是“行业”（Q268592）的实例（P31），如果它们涉及制造业，则可以是工业部门（Q8148）的一部分（P361）。 (Chinese)

As "class of human" is a metaclass, P31 is almost certainly meant instead. (English)
