 ### Message Rate
 
-Messages are the key data in EMQX. Messages are the data content being transmitted by all MQTT clients or real devices connected to EMQX. Clients or devices send or receive messages through topics as a way to complete data communication between them.
+In EMQX, messages represent the key data transmitted by all connected MQTT clients or real devices. Clients or devices send and receive messages through topics, enabling data communication between them.
 
 The card in the upper left corner of this overview page provides a clearer and easier way to monitor the rate changes in the current volume of messages incoming and outgoing in the system (message rate is measured in how many messages per second) by visualizing the rate spectrum with real-time rate values.

 ### Connections and Subscriptions
 
 As an MQTT broker, the number of connections and topics subscribed to EMQX is one of the most important metrics to observe. The connections are the number of MQTT clients or real devices currently connected to EMQX, the number of subscriptions is the total number of topics currently subscribed to in each client, and topics are the unique subscriptions.
 
-In the tab on the top right of the overview page, we can quickly see the number of connections, subscriptions, and topics in the cluster. The statistics in the card will be updated in real-time when a connection or a subscription topic is updated.

 Subscriptions are differentiated by client, while topics are unique subscriptions and the same topic may be included in different clients.

 In addition to providing real-time statistics, the bottom of the page also provides a visual chart that allows you to view historical and current changes in the number of connections and subscriptions by time (the time format: YYYY/MM/DD HH:mm), which allows you to monitor the trend of the number of connections and subscriptions within the entire EMQX cluster more clearly and intuitively. Hovering over the chart and clicking the icon in the top right corner allows you to enlarge the chart.

 ## Launch Dashboard
 
 EMQX Dashboard is a web application that listens to port `18083` by default. After installing EMQX successfully, you can access and use the EMQX Dashboard by opening <http://localhost:18083/> (replace localhost with the actual IP address if deployed on a non-local machine) through your browser.

+For users who have installed EMQX for the first time, you can use the default username `admin` and default password `public` to log in web page after opening the Dashboard in your browser.
 
 After logging in for the first time, the system will automatically detect that you are logging in with the default username and password, and will force you to change the default password, which is good for the security of accessing Dashboard, note that the changed password cannot be the same as the original password, and it is not recommended to use `public` as the login password again.

 ### 连接数和订阅主题数
 
 EMQX 作为一款 MQTT 服务器，其连接数和订阅主题数是整个系统中最为重要的观测数据指标之一。连接数是指当前 MQTT 客户端或真实设备连接到 EMQX 的数量，订阅是当前每个客户端中订阅主题的总数，而主题数是当前存在于 EMQX 集群内，所有客户端订阅过的主题总数。
 
 在概览页面的右上方的卡片里，我们可以快速的查看到整个集群内的所有的连接数，订阅数和主题数。当有连接或订阅主题更新时，卡片内的统计数据将会实时的更新。

 ::: tip
+
 订阅是按客户端区分的，而主题是唯一的订阅，同一主题可能包含在不同的客户端中。
+
 :::
 
 除提供直观的实时数字统计的显示外，在该页面的底部还提供了可视化图表的展示，可以通过时间变化来查看历史和当前的连接、订阅主题数的变化（时间单位精确到年月日时分），从而可以更好的帮助用户能够更加清晰直观的监控到整个 EMQX 集群内连接和订阅主题数的变化趋势。将鼠标移动到图表右上角可以通过点击图标来放大图表。
