Can I find serious relationship here?

Sure just be honest about who you are and where you are for a start.

Be ready to prove the same if someone asks because of all the scammers on this site.

If you can do both of those you should get by fine.

Hello Ting, I think it is possible to find your love online HOWEVER you must pay attention to every action and mannerism that person displays. It is hard finding a true to themself person in the cyberspace we look for love in. There are a lot of scams and fake people online, and to not fall into the traps is a full time job. It is not the same as having a coffee together and watching the eyes and actions of an individual. Text can be quite deceiving at times.
Be careful with your search and always play safe.
