   <!-- Answer -->
   To address the "Undefined vertex label: '?'" error you're encountering in 
Hubble 1.5.0, it's crucial to ensure that the vertex label '地点' is correctly 
defined in your graph schema. This error typically occurs if the vertex label 
hasn't been predefined or there's a mismatch in the label name. Here are the 
steps to resolve this issue:
   
   1. **Verify Vertex Label Definition**: Make sure the vertex label '地点' is 
properly defined in your schema. You can use HugeGraph's schema management 
tools or API to define or check the vertex label.
   
   2. **Check Encoding and Locale Settings**: Ensure your environment supports 
UTF-8 encoding and, if necessary, set the locale to support Chinese characters 
(e.g., zh_CN.UTF-8). This is important for Hubble to correctly parse and 
recognize Chinese characters.
   
   3. **Ensure Compatibility**: Confirm that your Hubble version is compatible 
with the HugeGraph server. Version mismatches can lead to unexpected errors, 
including issues with character encoding.
   
   4. **Use Schema Validation Features**: If available, utilize HugeGraph's 
schema validation to identify any inconsistencies or issues in your graph 
schema that might be causing errors.
   
   For future operations, consider using HugeGraph-Loader for data import 
tasks, as it supports a wide range of data sources and ensures compatibility 
with your HugeGraph server. Regularly review your graph schema, check system 
settings for encoding and locale support, verify compatibility before updates, 
and monitor logs for potential issues.
   
   For detailed steps on schema definition and validation, refer to the 
HugeGraph documentation and API guides.
