In 1993, Lin Wanxing became the first woman on the Guangxi-Guangdong route to obtain a Class B driving license and work as a truck driver. After a cargo owner deliberately set her up with an overloaded shipment, resulting in a fine, false accusations, and the seizure of her cargo, she was blacklisted by the industry and lost her livelihood. Refusing to give in or compromise, she steadfastly upheld industry regulations and gathered evidence along the way. She exposed the scheme of concealing expensive timber in mixed shipments and the industry's unspoken rules of cargo monopolization. Ultimately, she helped bring about comprehensive reforms to freight routes, securing a fair working environment for independent truck drivers and proving that staying on the right path and following the rules is the surest way to make a living.
