+# 标签版本与系统版本对应对应关系说明
+
+系统版本号指的是操作系统及其版本号,系统名与版本号之间以英文字符“-”连接,不能包含空格,最多64字符,随软件版本变更。其API接口名为GetOsFullName()。
+
+OpenHarmony历史发布的1.1.x/3.0.x/3.1.x标签版本采用3位版本号命名,系统版本号采用4位命名,导致历史发布的版本所显示的系统版本号与标签版本号规则不统一。为避免造成困扰,我们对社区已发布的版本及其标签的对应关系整理成下表。
+
+## 标签版本号与系统版本号对应关系
+
+| 标签 | 小型/轻量系统版本号 | 标准系统版本号 | 备注 |

+## 系统版本号修改方法
+
+### 1.0.x/3.0.x/3.1.x版本修改方法
+
+1.0.x/3.0.x/3.1.x版本上社区未做集成配置,小型/轻量系统和标准系统需要在不同文件上修改配置。
+
+小型/轻量系统OsFullName修改文件路径:startup_syspara_lite/ frameworks / parameter / src / parameter_common.c
+
+标准系统OsFullName修改文件路径:startup_syspara_lite/ interfaces / innerkits / native / syspara / src / sysversion.c
+
+修改static const int MAJOR_VERSION、static const int SENIOR_VERSION、static const int FEATURE_VERSION、static const int BUILD_VERSION字段为对应系统版本号即可。
+
+### 3.2.x及之后版本修改方法
+
+3.2.x及之后版本修改文件路径: startup_init_lite/ services / etc_lite / param / ohos_const / ohos.para
+
+修改const.ohos.fullname字段为对应系统版本号即可。
