The two main natural hazards of Hong Kong are mass wasting and flooding. I believe these hazards should be the priorities of Hong Kong due to their sub-tropical climate. In Hong Kong, the weather is warm and cool most of the year, depending on the season. However, in the summertime, the climate becomes hot and rainy; this is the wet season for Hong Kong. About 80% of rainfall occurs between May and September, and the average precipitation per year is 2400 mm(94.4 inches). The rain can be very violent, especially during June and August or tropical storms. With an excess amount of rainfall and Hong Kong's rapid urban development on hilly terrains, the environment has all sorts of reactions.
When there is too much water, the soil will become oversaturated, which significantly decreases the integrity of the ground and increases the chance of a mass movement happening. And the landslides of Hong Kong are usually fast and instantaneous rather than slow; this makes landslides in Hong Kong a hazardous event. In addition, surface runoff can occur when soil is oversaturated because precipitation exceeds the rate that the soil can absorb. As a result, there is a higher risk of flooding in low-lying areas.
Since flooding and mass wasting have a chance of happening simultaneously, I think they should be the country's main hazards to focus on mitigating. In fact, the government has already invested a lot of resources into mitigating such threats. Since 1995, the city has heavily invested $3.8 billion into projects that include nearly 1500 miles of drains, 225 miles of river channels, and four underground tunnels that span 13 miles. Additionally, there are four massive stormwater storage tanks implemented and 11 more developed for the future. The rainwater drainage system minimizes the erosion impact of heavy rainfall on hillside soil by redirecting and storing stormwater in containment tanks.
If I were to pick an area to help first, I'd pick locations closest to hazard zones. In Hong Kong's case, low-lying areas, places surrounded by hills, and coastal areas. These zones are at higher risk of flooding and landslides when there is heavy rainfall.
If I were to build a house in Hong Kong, I would do it at a high elevation. This way, I'd avoid the risk of flood damage and landslides. So the house would be either at a high cliff or closer inland and further from the coast, located away from hills, although there's is rarely any flat ground in Southeastern Asia.

This was a good final reflection on your country!
