Did Hong Kong people emigrate from Guangdong in the past year?

Provinces and ports are a family. Many Hong Kong people's ancestors came from Guangdong in War of Resistance against Japanese Aggression's time. After the war of liberation, many coastal cities or dignitaries immigrated to Hong Kong, which intensified the cultural integration, but it was still a province and a port on the whole. Especially now, Hong Kong has influenced Guangdong. For example, many English words have been added to Cantonese.
