Is there a through train from Gong Ming Bus Station to Houjie? What's the fare and how long will it take to get there?

About an hour and a half. Take a long-distance bus from Shenzhen-Shenzhen Gong Ming Bus Station and get off at Dongguan Bus Station, then walk to Dongguan Bus Station (inside the station) and transfer to bus 107 (you can stop only if you raise your hand without a stop sign, and get off at Houjie Station (outside the station)). Go straight for about 390 meters to Dongguan-Houjie Bus Station.
