In 2019, CULR collaborated with the Hong Kong Federation of Trade Unions to organize a summer social practice activity in Hong KongSAR, sending a delegation of CULR teachers and students to Hong Kong SAR for practice and exchange.

This activity was carried out following the signing of a cooperation memorandum between CULR and the Hong Kong Federation of Trade Unions in early 2019. It was an exploratory and practical exchange activity that contributed to cooperation in cross-regional exchanges, industry visits, and mutual support between the two parties. It not only expanded the social influence of CULR but also laid a more solid foundation for future visits and cooperation.
