How to buy Cryptos with AliPay on Binance?

Could you please elaborate on the process of purchasing cryptocurrencies using AliPay on the Binance platform? I'm particularly interested in understanding the steps involved, any potential limitations or restrictions, and any security measures Binance employs to safeguard user transactions. Is this process secure? What types of cryptos are available for purchase using AliPay? Also, how does the pricing work and are there any additional fees involved? I'd appreciate a detailed explanation to help me navigate this process smoothly.
