"The road of life is tortuous" means that people will encounter all kinds of challenges, difficulties and twists and turns in their life journey. Life is not always smooth sailing, but full of ups and downs and twists and turns. The next sentence "Pursue persistently, and you will eventually achieve your goal" encourages people to pursue their goals and dreams persistently. Although the road of life is full of twists and turns, as long as we make unremitting efforts and constantly pursue our goals, we can finally achieve our goals.
