Hello mimirong. Unfortunately I´m not good at Chinese so I need to use translator. From that I could only guessing what these words really mean together.
This is what I get:
"Enemy player killed you and after that you started to spectate another player."

• That´s fine, this is how it should work. What came next? From translation I get that you took control of spectated player character. Did you? Or I really don´t know what you mean by that. For better understanding, please, use English.
