Bat lau dung laai is a Hong Kong Cantonese corruption of the Vietnamese phrase bắt đầu từ nay, meaning "from now on" ( = begin, start; = "from", = "now", in Vietnamese pronounced as /ʔɓat̚˧˦ ʔɗəw˨ tɨ˨˩ naj˧˧/).[1]
The phrase was made famous in the 1980s and 1990s in Hong Kong, due to a Vietnamese-language radio public service announcement that was broadcast, nearly hourly, on public radio broadcaster RTHK.[1]
The broadcast was first made on 16 August 1988, which announced the government's decision to implement a screening policy that would separate refugees from non-refugees (or boat people with economic motivations).[2] The statement was read by Chung Wai-ming, a well-known RTHK radio personality.[3] The Vietnamese portion of the broadcast was read by a Vietnamese boat person who was about to be repatriated.[4]
The radio announcement began with a sentence in Cantonese, the most commonly spoken Chinese variant in Hong Kong.
香港[政府]對越南船民已經實施甄別政策。跟住嗰段越南話廣播，就係向佢哋講述呢個政策嘅內容。[2]
This was then followed by a paragraph in Vietnamese.
Bắt đầu từ nay, một chính sách mới về thuyền nhân Việt Nam đã được chấp hành tại Hồng Kông. Từ nay về sau, những thuyền nhân Việt Nam kiếm cách nhập cảnh Hồng Kông với thân phận những người di tản vì vấn đề kinh tế sẽ bị coi là những người nhập cảnh phi pháp. Là những người nhập cảnh phi pháp, họ sẽ không có chút khả năng nào để được đi định cư tại nước thứ ba, và họ sẽ bị giam cầm để chờ ngày giải về Việt Nam.[2]
After that, the announcement ended with another sentence in Cantonese.
剛才嗰段越南話廣播，係向企圖進入香港嘅越南船民，講述香港對佢哋實施嘅甄別政策㗎。
The first sentence in Cantonese Chinese:
The message in Vietnamese:
The final sentence in Cantonese Chinese:
Due to the frequency of the broadcast, many Hong Kong people came to learn the phrase. Some, however, mistook the phrase as a term of greeting,[5] similar to sawasdee in Thai.[1] The phrase eventually became a metaphor for Vietnamese people and even Vietnamese culture.
The term is now considered to be a derogatory slur for Vietnamese people.[1]
The first recorded instance of the usage of "Bắt đầu từ nay" in Hong Kong entertainment programmes was during the 1980s, when it was used in a segment of the light entertainment show Enjoy Yourself Tonight. In the segment, a fight in the refugee camp was parodied, and two actors, using the stage names "Bắt đầu" and "Từ nay", roughed up one of the audience (played by an actor) in the "Legislative Council" meeting who was well known for creating commotions during Legislative Council meetings.[6]
During the 1990s, some asylum seekers managed to use self-made tools to cut through the fence around the refugee camps and escaped. This incident was replayed on RTHK's news parody programme Headliner. In the video, the phrase was split into the following
In the 2000s, Vietnamese cuisine became popular in Hong Kong, and the phrase, which had faded out of memory after the resolution of the refugee problem, resurfaced in an advertising campaign for a Vietnamese restaurant.
The phrase was used at least twice during the 2010s on books.
