The tor is blocked before our 60th national day. but you can fix the problem by add bridges to your torrc.

Bridge relays (or "bridges" for short) are Tor relays that aren't listed in the main directory. Since there is no complete public list of them, even if your ISP is filtering connections to all the known Tor relays, they probably won't be able to block all the bridges.

Configuring more than one bridge address will make your Tor connection
more stable, in case some of the bridges become unreachable.

A way to find public bridge addresses is to send mail to bridges@torproject.org with the line "get bridges" by itself in the body of the mail. You'll need to send this request from a gmail account, though — otherwise we make it too easy for an attacker to make a lot of email addresses and learn about all the bridges. Almost instantly, you'll receive a reply that includes:

Here are your bridge relays:

 bridge 60.16.182.53:9001 c9111bd74a710c0d25dda6b35e181f1aa7911133
 bridge 87.237.118.139:444 c18dde4804e8fcb48464341ca1375eb130453a39
 bridge 60.63.97.221:443 ab5c849ed5896d53052e43966ee9aba2ff92fb82

Add "UseBridges 1" and the lines before to /etc/tor/torrc. Restart the tor service. Then it should be ok now.

Another way to find public bridge addresses is to visit https://bridges.torproject.org/. The answers you get from that page will change every few days, so check back periodically if you need more bridge addresses.
