Most people actually give up on their dream of learning Chinese or any second language because traditional classroom instruction is just too much of a hassle. Online classes are an option but sometimes even limited data plans and or not having enough minutes of Internet use can derail the dream of learning a new language. Learning Chinese through PDF lessons can dramatically reduce your data use. Once a lesson or tool is downloaded, you can then access it offline via your computer or smartphone any time or place regardless of Internet access. So not only will learning Chinese using PDF lessons save minutes on your data plan—it will save you some significant time as well as the lessons add up.
