A friend from Yichang came in for help.

There is an aunt who starts with 87. The aunt who cooks in our dormitory is PHS starting with 87, and she is really from Yichang. Because I am a clerk, I have the most contact with my aunt. My aunt calls me if she needs anything, so I can recite her PHS number backwards! It is suggested that you use Yichang local landline or other PHS to call China Telecom's toll-free customer service number 10000 for detailed consultation. So the answer you get must be the most accurate ~! I hope my answer can help you! !
