Zhang Wei was a guest actor in iPartment 3. He played a supporting role in the series and contributed to the development of the plot. Although his appearance time was not long, his performance was outstanding and left a deep impression on the audience. As iPartment 3's storyline was more complicated, it was also challenging for the guest actors to act. In order to fully display the character's characteristics and acting skills in a short period of time, guest actors needed to adapt to the character setting and plot requirements in a short period of time and carefully plan and prepare. In addition, the remuneration of guest actors was also related to the importance of the role. Due to the development of iPartment 3's plot, the guest actors had a relatively short appearance time and the character setting was not particularly eye-catching, so their pay was relatively low, which also led to Zhang Wei becoming a guest actor.
