Hi I'm coming from shenzhen airport to Tangquan Boluo Huizhou Guangdong Province 516100 China.

Actually, shuttle bus no. 330C does exist. I just checked the official website of the airport. And the bullet train takes you to Huizhou South, which is almost 70km to your destination. It is not the best way to go.

I would suggest you take a direct intercity bus from the airport to Huizhou Bus Station first. Then transfer a long-distance bus to arrive at Boluo County. This one is easier for you.
