According to the posthumously published memoirs of veteran Hong Kong political figure and leader of the Alliance,
Szeto Wah, Yellowbird was financed mainly by Hong Kong businessmen and celebrities who sympathised with the plight of the activists, but extensive assistance also came from the colonial government. The organizers of the operation spent upwards of HK$600,000 (US$64,000) to rescue each activist and to cover other expenses to get them abroad. In addition,
triad members who managed the smuggling routes inside China requested payments of about US$25,000 for every attempt, regardless of its success or failure. Other benefactors included chanteuse
Anita Mui and filmmaker
Alan Tang. Within China, considerable financial backing for the operation came from a variety of sources, such as business personalities and ordinary citizens who sympathized with the activists. Diplomats in Hong Kong were also able to help by obtaining visas for the escapees' departures to various countries. Funds were used for the costs of smuggling individuals directly out of mainland China, as well as for financial assistance for other dissidents who made it to Hong Kong by themselves. Rescue money was mainly raised privately by the Operation, for fear of alerting British authorities at the time, who were being careful before
Hong Kong's transfer to China in 1997. There were worries about possible repercussions from Beijing if any knowledge of assistance given to the dissidents was revealed. Nonetheless, Yellowbird managed to gather funds of around US$2,000,000 from the business community in its early beginnings. ==Success and details of the operation==
