At the Supreme Command, soldiers in purple participated in card stunts in the form of No.60 in Thai to mark her birthday. Staff from the Udon Thani Municipality office also performed the same card shows at Nong Prachak in the northeastern province.
The princess celebrated her birthday by releasing 590,000 fish into the Chao Phraya River at Wasukree Pier.
Her dedication to a better life for all Thais is recognised by other countries, including the United States, as US Secretary of State John Kerry sent her a birthday message on behalf of President Barack Obama and American citizens. (See here)
"Her Royal Highness has admirably devoted her life to the service of the Thai people. She is a generous patron of her country's poor, supporting development projects in education, health, hygiene, water resources, and agriculture. She is also an accomplished scholar, and for much of her life has been a dedicated teacher of history for her country's emerging leaders,'' he said in the message.
"We wish Her Royal Highness all the very best on this auspicious occasion, and reaffirm our friendship and express our support for the Thai people,'' he wrote.
