Hi. I have stay at 9 hours at hong kong airport? Where should i have to visit in this time and how??

You are advised to visit Tsim Sha Tsui area. Taste some local foods and have a taste of unique local conditions and customs. Upon landing, take airport express to Tsing Yi Station. Then take Tung chung line to Lai King and transfer to Tsuen wan line to the destination. In addition, remember to go back to the airport at least 2 hours in advance before the departure.

What is the things to visit in this areas where you mentioned?

Tsim Sha Tsui is known as the one-stop shoppers’ paradise brimming with both high-end malls and bustling shopping streets. There are also various themed museums that inject a little cultural atmosphere to the area. After sunset, enjoying the brilliant night scenes along the Victoria Harbour can be a great way to end the evening.
