I make a visa in third country. Is the chances to get the visa good?

I am a foreign student in Malaysia. My friend invited me to visit and go together to China (my friend is a Chinesse, and i'm goin to stay in her place), so i make a visa in third country. Is the chances to get the visa good? and i booked the ticket to tianjin, but i want to return to Malaysia using through Guilin, is it risky?
