What cultural faux pas should I try to avoid making in Sai Ying Pun?

"In Sai Ying Pun, it's important to respect the local customs and traditions. Avoid pointing with your index finger, as it's considered rude. Instead, use your whole hand to gesture. When using chopsticks, never stick them vertically into your bowl of rice, as this is reminiscent of a funeral ritual. Also, don't tap your chopsticks on the edge of your bowl, as this is something beggars do to attract attention. Avoid discussing sensitive political topics, such as the relationship between Hong Kong and mainland China. This can be a sensitive issue and it's best to steer clear of it unless you're well-informed and can discuss it respectfully. In Hong Kong, punctuality is highly valued. Being late for appointments or meetings is seen as disrespectful. When giving or receiving gifts or business cards, use both hands. It's considered polite and shows respect. Avoid wearing revealing clothing, especially when visiting temples or other religious sites. Dress modestly to show respect for local customs and traditions. Public displays of affection are not common in Hong Kong, so avoid hugging, kissing, or holding hands in public places. Lastly, remember to always say "please" and "thank you". Politeness is highly valued in Hong Kong culture," said another expat in Sai Ying Pun, Hong Kong.
