If you own 80shidai.tk just fill in the form then change nameservers to:

ns1.freetzi.com   69.162.65.130 (provide ip only if required)
ns2.freetzi.com   69.162.65.131 (provide ip only if required)

With our nameservers you will get full email support (IMAP, POP3), powered by Google Apps. Check the tutorial.

If you only want to point A record to us (recommended for Chinese users)
use ip 69.162.65.133.

最下面说如果你只想添加A记录，建议中国用户使用69.162.65.133。

那么我在绑定TK域名的时候，应该选第2个用TK免费服务器像这样填

按照它提示If you only want to point A record to us (recommended for Chinese users)
use ip 69.162.65.133.为了适合中国用户好像应该这样填吧。HOST NAME里是填www.80shidai.tk还是80shidai.tk啊？

还是第3个像这样

请高手帮个忙，多谢了。另外我看论坛里很多用TK域名的都没有主机名"WWW"，不能添加这个吗？
