As we all know, Pacha Rajiti Yapa is the eldest princess of King Rama X of Thailand. Born on December 7, 1978, she is now a civil servant of the Thai government. Although she still has not married, this does not matter. She has noble royal medals, which are the most precious treasures in her life.

Phachalajitiyapa was born on December 7, 1978. His mother was Vajiralongkorn's first wife and the first princess in the era of Crown Prince Vajiralongkorn. She was a Thai nobleman. But not long after Vajiralongkorn married her mother (when she was about 2 years old), she fell in love with another woman and gave birth to 4 children and 1 daughter. However, because this woman still maintained a lover relationship with the crown prince when the crown prince had a wife, she was not accepted by the Thai royal family and did not get a title. Except for the youngest daughter, the other 4 children she gave birth to have no royal titles and have been living in the UK.

Vajiralongkorn and Pachalajitiyapa's mother divorced, but did not stay with her lover. Instead, she married a second princess and gave birth to a grandson, which is the current crown prince of Thailand.

Pachalajidiyapa's mother Songshavali and Vajiralongkorn divorced, and still maintained the royal title. Although they were not princesses, they also received the title of aristocratic title like "Madam". After all, her father is the brother of Queen Mother Sirikit . Songshawali actively manages royal internal affairs in Thailand and still has a high status in the royal family.
