BTCF meaning in General ?

Buddhist Compassion Relief Tzu Chi Foundation, Republic of China, known for short as the Tzu Chi Foundation (Chinese: 慈濟基金會; pinyin: Cí Jì jījīn huì; lit. '"Compassionate Relief Foundation"'), is a Taiwanese international humanitarian and non-governmental organization (NGO). The foundation has several sub-organizations such as the Tzu Chi International Medical Association (TIMA) and also the Tzu Chi Collegiate Youth Association (Tzu Ching) (Chinese: 慈濟大專靑年聯誼會 (慈靑)). Tzu Chi volunteers and relief workers are mostly recognizable by their blue and white uniforms called, in Chinese: 藍天白雲, lántiān báiyún, (lit. 'blue sky, white clouds'). The foundation's work includes medical aid, disaster relief, and environmental work such as recycling. It is operated by a worldwide network of volunteers and employees and has been awarded a special consultative status at the United Nations Economic and Social Council.

The Tzu Chi Foundation was founded by Cheng Yen, a Taiwanese Buddhist nun, or bhikkhuni, in 1966 as a Buddhist humanitarian organization. The organization began as a group of thirty housewives who saved money for needy families. Tzu Chi gradually expanded its services over time, opening a free medical clinic in 1972 and building its first hospital in 1986. The organization underwent a rapid expansion in the late 1980s and early 1990s, coinciding with a surge of popularity in Humanistic Buddhism in Taiwan. In the 1990s the organization started major international disaster relief efforts. Tzu Chi is known for undertaking long-term projects such as building new homes, schools, hospitals, and places of worship (including churches and mosques for non-Buddhists) for victims following a disaster. As of 2013, the organization was estimated at over 10 million members worldwide throughout 47 countries.

Tzu Chi has a policy of being secular in its humanitarian work, however Dharma teachings are often integrated into its practices for volunteers. Cheng Yen is considered to be one of the "Four Heavenly Kings" of Taiwanese Buddhism, and Tzu Chi itself is considered to be one of the "Four Great Mountains", or four major Buddhist organizations of Taiwan along with Fo Guang Shan, Dharma Drum Mountain, and Chung Tai Shan.
