需要实现的功能：

– 应付账款（1.给材料供应商 2.给商品销售方 4.银行应还的贷款）

– 应收账款（1. 向购货方收取购买商品的账款）

– 员工费用管理（1.给员工发薪水和应扣除的税 2. 给员工报销：根据不同部门和岗位提供不同的报销额度。我发你的HR部分有设计不同部门，正好给关联上，上次的只有depart，这次加一个position，给个level1~5，按照不同部门和position给不同的报销额度，能实现么）


做出来大概要这个样子：Run的时候1. HR系统  2. 财务系统 然后每一项里面有1234。。。。（我之前自己写的第1部分写的不好，功能虽然都实现了，但是写死了，需要麻烦你帮我改动一下哈）


要求提到需要Interplay with HR module，然后要用到singleton pattern（单例模式）。
