In a large pot, heat the chicken broth over medium-high until it simmers; add green onions.
Whisk together cold water, cornstarch, soy sauce, and sugar in a bowl. Stir this mixture into the broth, bringing it to a boil before letting it simmer for 1 minute. Reduce heat to medium-low.
In a small bowl, whisk eggs with remaining cold water until combined. Slowly drizzle the egg mixture into the hot broth, removing the pot from heat as you go. Serve immediately.
