Short version: I bought a Xiaodu WiFi for 9 yuan, using a JD free-shipping coupon. Even so, the kaomoji on my keychain cost more than this thing… So, according to the official site, you’re supposed to install Baidu’s software, which bundles a one-click idiot-proof driver. One button and your current network is shared out. It’s really just a wireless adapter in hotspot mode. Which means there has to be a way to use the Xiaodu WiFi as a plain wireless adapter, because that’s what it is.
