The government has readjusted its feng shui at Government House according to Chinese cosmological understandings to enhance luck and prosperity.
The readjusting is also aimed at creating peacefulness.
Six potted plants of one species were placed on the lawn in front of the Thai Ku Fah Building, opposite its entrance, where Prime Minister Abhisit Vejjajiva enters the Government House compound.
The placement of plants is believed to avoid and drive away bad luck.
It is also believed the bright colours of the plants, yellow and green, are to enhance luck and prosperity and to create unity as well as bringing out the honest and boost charisma.
The feng shui at Government House had previously been adjusted once.
A Happy Buddha was invited on the rooftop above the PM's office and round marbles were decorated at several spots of the Thai Ku Fah building to fend off bad luck and enhance good luck and prosperity.
Feng shui is an ancient Chinese system of aesthetics which applies the laws of astronomy and geography (or heaven and earth) to decorate the homes and offices of its believers in
order to help them improve their lives and living conditions as well as to avoid and eliminate bad luck.
In 2008, yellow shirts protesters seized Government House compound for six months in order to oust the then Samak Sundaravej and Somchai Wongsawat governments, branded by the movement as proxies of deposed prime minister Thaksin Shinawatra.
PAD protesters occupying Government House were impacted by a number of small explosions, injuring many demonstrators and security volunteers.
Major casualties occurred in November 2008 when one protester was killed and 22 others wounded at after an apparent M79 grenade attack at the Yellow-Shirt encampment.
The long-standing occupation of Thailand's seat of government was lifted in early December 2008 when the protesters moved to rally at the country's two main airports to pressure the Somchai government.
Despite the end of the yellow shirt demonstrations, the rival United Front for Democracy against Dictatorship (UDD) or the red shirts often took their protests to Government House demanding Prime Minister Abhisit Vejjajiva dissolve the parliament.
