--   postalCode: '10001'

-- - type: home
--   number: '212-555-1234'
-- - type: work
--   number: '646-555-5678'
+data1:
+  Name: John
+  age: 30
+data2:
+  Name: John
+  age: 20
+diff: |2
+    Name: John

+  - age: 30

 然后，对应配置的 diff 如下：
 
 ```

+data1:
+  Name: John
+  age: 30
+data2:
+  Name: John
+  age: 20
+diff: |2
+    Name: John
+  + age: 20
