Alternative to google scholar in China Are there any valid alternatives to google scholar?

I am currently living in China. almost the whole internet is blocked, including Google. I tried to bypass the firewall, then google scholar tends to deny my access claiming that the traffic is suspicious. 

Are there other valid alternatives to google scholar where I can easily search for random scientific papers from different fields and trace their citations Thanks!
