How to access US yahoo email yahoo.com after being stuck in mail.cn.yahoo.com

When I came back from China

again i can not access to yahoo email in Singapore

and end up stuck to the same page that my email has been migrated

http://cn-mg6.mail.yahoo.com/neo/trapcn?a=eol

I did report [Incident:130822-034804] but I solved the problem by myself

(so some how the intelligent yet stupid yahoo routers know I 

have access mail.cn.yahoo.com last few days)

I did access yahoo while i am in China

as to send out email or share infor

So today

on PC i clear all history data in Chrome browser

(run as administrator) under the advance setting

(I only try clear the history data for past 4 weeks)

Also under the yahoo profile, I ensure my location is set at Singapore

I was luckily to read back US yahoo email while back Singapore

The on hp YMail application

I clear data and cache

Then I re-login to mobile yahoo

and I know I sure can read the yahoo email in US

and also let yahoo router know that I am in Singapore now

Lastly on PC login to www.yahoo.com

Then finally goto yahoo home page

on left panel and choose more sites

and access Mail from there

There be some shortcut in between

But my experiences tell me to clear all caches and data on yahoo servers

Hope this way can help others that got the same unique problems

as none Alibaba or US yahoo helpdesk able to help on this

Will monitor the situations

Now my yahoo email interface is still in Chinese
and the access email server is http://cn-mg61.mail.yahoo.com

So is still waiting for answer from
Yahoo! Customer Care <customercare-en@cc.yahoo-inc.com> and
ymail@service.cn.yahoo.com

It is a sad thing that yahoo services was not as good as before
