Hi,I want to go to shenzhen from macau. how to go & cheap way which one?

The easiest mode is to take a ferry from Macao Maritime Ferry Terminal to Shekou. From 09:45 to 20:45, there are about 11 ferries available. The travel time is about 60 mins, which is also the fastest way. The fare is CNY200 for economical class cabin and CNY300 for first classcabin.

But ferry is not the cheapest way. I suggest you take a hotel free shuttle bus, or city bus from your location in Macau to Barrier Gate. Cross the border to Zhuhai Gongbei. Then walk to the nearby Gongbei Long-distance Bus Station to take a bus to SZ in 2.5-3 hours. The fare is only CNY100 per person.
