What cultural faux pas should I try to avoid making in Repulse Bay?

"In Repulse Bay, it's important to respect the local customs and traditions. Avoid discussing sensitive topics such as politics, especially issues related to China and Hong Kong's relationship. When visiting temples or religious sites, dress modestly and refrain from taking pictures without permission. It's also considered disrespectful to point at religious statues or touch them. In restaurants, don't stick your chopsticks upright in your rice bowl as it's associated with funerals. Also, if you're not using your chopsticks, place them on the chopstick rest or across your bowl or plate, not on the table. Avoid littering as Hong Kong has strict laws about cleanliness. Also, refrain from smoking in public places as it's banned in most areas. Hong Kong people value personal space, so avoid touching people unless you know them well. This includes avoiding patting someone on the back or touching someone's arm during conversation. When giving or receiving something, use both hands. This is seen as a sign of respect. Lastly, punctuality is highly valued in Hong Kong. Being late for appointments or meetings is considered rude and disrespectful," said another expat in Repulse Bay, Hong Kong.
