Just to give more Clarification to the Question by the OP:
the OP is a Student in China and applying for a Thai E–Visa at the Thai Consulate in Shanghai (China)
the Thai Consulate in Shanghai is asking for something (Declaration Voucher of Overseas Personnel's Accommodation Registration in China) that all Residence Permit Holders in China (including students) would already have had and
was kind enough to provide the English Language Link to the Shanghai Municipal Gov't information about this Declaration Voucher of Overseas Personnel's Accommodation Registration
the Thai Consulate in Shanghai is asking about something from China's National Immigration Administration, not something from Thai Immigration
Hopefully, the OP understands where (China government website/app) to obtain what is requested from the Thai Consulate in Shanghai
You selected the WRONG Thai E–Visa Subtype on the Thai eVisa website....
Looks like you want to get the Non–O Married to a Thai Wife: or, on the Thai eVisa Website it is = Non–immigrant (O) To Stay with Thai Family Residing in Thailand (more than 60 days),
BUT, you had most likely INCORRECTLY selected Non–immigrant (F) Family or Dependent of Diplomatic Officers/Officials based in Thailand
Do check and verify again that you had selected the correct Thai E–Visa Subtype from the initial window/menu
