The UnionPay deposit page typically lists multiple sub-channels (such as UnionPay 1, UnionPay 2, UnionPay 3, etc.), with each channel corresponding to different single transaction limits.

Selection Method: In the currency dropdown on the deposit page, select [UnionPay], and the system will display each channel and its corresponding single transaction limit range. Please select the channel whose amount range covers your deposit needs based on your actual deposit amount this time.

Amount unit explanation: K = thousand (500K = 500,000 yuan), M = million (1M = 1,000,000 yuan). If the current channel shows unavailable, you can try switching to another channel or use USDT/USDC instead.
