Split initiator : the party initiating the split, in this case electronic business platform;
Sub-account party : the direct payee of the transaction, the secondary merchant of the e-commerce platform;
Recipient : The party receiving the funds, the e-commerce platform has been added as the receiver by default, and the second-level merchants can directly subscribe to the e-commerce platform; for other receivers, the e-commerce platform establishes a unified platform dimension by adding the sub-account receiver interface "Sub-account recipient list", after successfully added, all secondary merchant accounts can be distributed to them. The recipient can be a WeChat Pay merchant or a WeChat Pay personal account.
1) 30% split account ratio
微信分账的比例上限在30%，即针对一笔交易订单，平台商户最多只能把交易资金的30%进行分账，
而平台要留存该笔交易订单70％以上的资金，所以对于只需要收取很小比例额度服务费的平台而言，
微信分账并不适用这种的业务场景；
* Of course, there is another way to use the receiver as a sub-accounter, but if there are more receivers, the e-commerce platform needs to maintain a sub-account list, and each order transaction fund goes to the designated account.
2) WeChat split account period
微信分账账期最长为30天，如果30天内未进行分账的话，微信会把交易资金自动解冻至平台，同时不再继续分账。
Note: If the e-commerce platform needs other payment methods such as Alipay and UnionPay in addition to WeChat payment, the splitting function of WeChat payment alone cannot meet the business needs of the platform, so many e-commerce platforms will specifically connect to a payment platform .
