 The schemaless writing method creates super tables and their corresponding subtables. These are completely indistinguishable from the super tables and subtables created directly via SQL. You can write data directly to them via SQL statements. Note that the names of tables created by schemaless writing are based on fixed mapping rules for tag values, so they are not explicitly ideographic and they lack readability.
 
+Tips:
+The schemaless write will automatically create a table. You do not need to create a table manually, or an unknown error may occur.
+
 ## Schemaless Writing Line Protocol
 
 TDengine's schemaless writing line protocol supports InfluxDB's Line Protocol, OpenTSDB's telnet line protocol, and OpenTSDB's JSON format protocol. However, when using these three protocols, you need to specify in the API the standard of the parsing protocol to be used for the input content.

 无模式写入方式建立的超级表及其对应的子表与通过 SQL 直接建立的超级表和子表完全没有区别，你也可以通过，SQL 语句直接向其中写入数据。需要注意的是，通过无模式写入方式建立的表，其表名是基于标签值按照固定的映射规则生成，所以无法明确地进行表意，缺乏可读性。
 
+注意：无模式写入会自动建表，不需要手动建表，手动建表的话可能会出现未知的错误。
+
 ## 无模式写入行协议
 
 TDengine 的无模式写入的行协议兼容 InfluxDB 的 行协议（Line Protocol）、OpenTSDB 的 telnet 行协议、OpenTSDB 的 JSON 格式协议。但是使用这三种协议的时候，需要在 API 中指定输入内容使用解析协议的标准。
