Sharing about the first time participating in blood donation, he said that in 2013, when he was a technical officer of Hang Nguyen Iron and Steel Company, he was invited to participate in the activities of the Tuyen Quang Red Drops Club in order to supporting the Red Journey of the National Institute of Hematology and Blood Transfusion held in Tuyen Quang Province. After that, he became a volunteer of the club. He also actively participated to supports blood donation and directly donated blood at the activities of the club.

In 18 times of blood donation, he donated blood directly 8 times to emergency patients. Once, he directly donated blood to people suffering from stomach bleeding. Another time, Chiem Hoa District held a voluntary blood donation day. However, out of the hundreds of blood units received, there was no blood type AB. After receiving the information, he crossed a distance of nearly 70 km by motorbike from Tuyen Quang City to Chiem Hoa to donate blood, contributing to the success of the festival.

Recently, Thinh was awarded a certificate of merit by the blood donation steering committee of Yen Son District for his outstanding achievements in the voluntary blood donation movement.
