In this presentation, we will present the Radio astronomy development since 2006 in Hong Kong. We will divide into 3 parts. Firstly, it is so called starting from zero. We will present the setting for the first steerable radio telescope and observation in a small area which is a business-oriented city by making use the commercial small radio telescope. Also, we will present the difficulties arising from technical aspects, radio noises stemming from one of the highest populated cosmopolitans and weather hazards in a subtropical region for achieving to get radio astronomy signals in Hong Kong.

Secondly, we would like to present some observational results for some strong radio sources in the 21cm frequency bands. These celestial objects were the 89% partial solar eclipse radio observation in 2020, strong sources in radio band by using OTF observational mode which was fit for a single dish observation.

Lastly, we would like to focus for the forthcoming observation in Pulsar observation in the local Hong Kong sky using another wavelength, namely the molecular lines observation in Hong Kong by using the 6cm frequency band. However, the most interesting observation that we would like to achieve is the 21cm Cosmology and the follow-up observation for the repeatable FRB in our local sky by using single dish method and radio interferometer. Of course, we appreciate very much if there is any possible international collaboration.
