附一个之前使馆的回复，对“3个月工资单 或 经济担保VE”的解释
Dear Sir or Madam,
this information sheets that is valid for all Schengen countries. Some
of these countries do not have a formal obligation - in these countries
instead of the VE the proof of income is necessary. As Germany does have
VE you should present it.
With best regards
