 Each actor concurrently processes tasks of the main thread. For each actor, there is a message queue and a single-thread execution module. The message queue receives requests from the main thread and other actors; the single-thread execution module serially processes requests, sends requests to other actors, and creates new actors. These isolated actors use the asynchronous mode and can run concurrently.
 
 ### Precautions
-- Currently, a maximum of eight workers can co-exist.
+- Currently, a maximum of eight worker threads can co-exist.
 - In API version 8 and earlier versions, when the number of **Worker** instances exceeds the upper limit, the error "Too many workers, the number of workers exceeds the maximum." is thrown.
 - Since API version 9, when the number of **Worker** instances exceeds the upper limit, the business error "Worker initialization failure, the number of workers exceeds the maximum." is thrown.
-- To proactively destroy a worker thread, you can call **terminate()** or **parentPort.close()** of the newly created **Worker** instance.
+- To proactively destroy a worker thread, you can call **terminate()** or **workerPort.close()** of the newly created **Worker** instance.
 - Since API version 9, if a **Worker** instance in a non-running state (such as destroyed or being destroyed) calls an API, a business error is thrown.
 - Creating and terminating worker threads consume performance. Therefore, you are advised to manage available workers and reuse them.
 - Do not use both **new worker.Worker** and **new worker.ThreadWorker** to create a **Worker** project. Otherwise, **Worker** functions abnormally. Since API version 9, you are advised to use [new worker.ThreadWorker](#constructor9). In API version 8 and earlier versions, you are advised to use [new worker.Worker](#constructordeprecated).
