Related to this post about Scheme 6000:
Since a few days all over Hong Kong you can find advertisings how to get the HKD 6,000 from
the government. The advertisings are everywhere:
In the MTR, on all MTR platforms, at the bus stations advertising panels + heavy TV presence on all main channels.
Wonder how much this advertising campaign costs & maybe if doing this a more humble way - how much money could be used for something more urgently / neccessary ?
Who is the advertising company getting this job done ?
Here a photo from Kwai Hing MTR platform:
