    CREATE (a)-[r:师傅] -> (b)
    RETURN r
    
    MATCH (a:X_Person),(b:X_Person)
    WHERE a.name = '孙悟空' AND (b.name = '猪八戒' or b.name ='沙悟净')
    CREATE (a)-[r:师兄] -> (b)
    RETURN r
    
    MATCH (a:X_Person),(b:X_Person)
    WHERE a.name = '猪八戒' AND (b.name ='沙悟净')
    CREATE (a)-[r:师兄] -> (b)

match (a: X_Person),(b:X_Wuqi)
    where a.name = '孙悟空' and b.name = '金箍棒'

    return r;
    
    match (a: X_Person),(b:X_Wuqi)
    where a.name = '沙悟净' and b.name = '禅杖'
    create (a) -[r: has] -> (b)
    return r;
    
    match (a: X_Person),(b:X_Wuqi)

    create (a) -[r: has] -> (b)

    CREATE (xyj_Fo:X_Fo{name:"普贤菩萨",age:99999})
    CREATE (xyj_Fo:X_Fo{name:"孔雀明王",age:99999})

创建佛教的角色属于佛教的关系
