China visa for transit to cruise

Hello, I am a Filipino who will go on a cruise. As soon as I land in Tianjin International Airport, I will rush to the Port of Tianjin to embark. The same procedure in returning to Tianjin on the last day of the cruise. I will rush to Tianjin Intl. Airport to catch my flight to Manila. Do I need a Chinese visa (double entry maybe)? Thank you.
