In this paper, we prove the existence of Hayman T directions of meromorphic functions. To achieve our purpose, we establish a fundamental inequality about the Ahlfors-Shimizu characteristic for an angle and explain that the inequality is best possible in terms of the existence of Julia directions and Hayman T directions.
