关于二级枚举的说明，为了节省查询速度，二级枚举是通过特殊算法生成的，原理为
凡是能被 500 整除的都是一级枚举，(500 * n) + 1 < em < 500 * (n+1) 为下级枚举
如：1000 的下级枚举对应的值为 1001,1002,1003...1499
对于 issign=1 的，表示这个类别只有一级枚举，则不受上面的算法限制
------------------------------------------------------------------------
更新算法:
新增二级枚举下添加"-N"自己类别选择,例如:
1001二级枚举下面的3级类目,则为1001-1,1001-2...
这时候需要issign=2
