Zhang Fei during the Three Kingdoms period was extremely brave and a figure that everyone is familiar with. His personality is a typical extrovert. For example, when he learned that his sworn brother Guan Yu had been killed, he was so angry that he wanted to send troops to attack the state of Wu overnight.
On the contrary, Xie An, the famous prime minister of the Eastern Jin Dynasty, faced the 600,000 army led by Fu Jian of the former Qin Dynasty with a mere 80,000 troops. After receiving the news of victory, he remained calm as usual and finished the chess game he was playing. After returning to his house, he was so happy that he kicked off his shoes. He can be said to be a typical introvert.
So whether your personality is introverted or extroverted, take this psychological test to find out.
