Yu'ebao (“Leftover Treasure”) lets consumers generate yield on un-utilized cash in their Alipay e-wallet, while still allowing the funds to be instantly available for everyday purchases. The minimum investment threshold to participate is RMB 1 ($0.15). It's a simple proposition but powerful given that the yield of ~1.7% is higher than most current account's interest rates. It is the biggest money fund product in the world by AUM as of June 2020.
