In 2016，Guangdong Province，Hong Kong SAR and Macao SAR had outstanding achievement in intangible cultural heritage protection. Besides，the number of cultural activities and academic conferences on intangible cultural heritage held in these three regions was increased rapidly，indicating that the academia is paying more attention to intangible cultural heritages in Guangdong，Hong Kong and Macao. But there are still some shortcomings in related researches，including as followed：firstly，academic interpretation of intangible cultural heritage protection was insufficient；secondly，researches on cultural identity were excessively concentrated on Cantonese opera and particular folk religions；thirdly，related researches were focused on the Guangfu culture，neglecting the culture of other ethnic groups，like the Chaoshan culture and the Hakka culture；and lastly，researches on the folk organizations of intangible cultural heritage protection were inadequate.
