What cultural faux pas should I try to avoid making in Tai Po?

"When visiting Tai Po, it's important to respect local customs and traditions to avoid any cultural faux pas. Here are some tips: Avoid discussing politics, especially issues related to Hong Kong's relationship with mainland China. This is a sensitive topic and can lead to heated debates. Do not spit or litter in public places. Hong Kong is known for its cleanliness and locals take pride in maintaining it. Avoid pointing with your index finger, as it is considered rude. Use your whole hand instead. Do not take photos of people without their permission. This is considered disrespectful and invasive. Avoid touching people, especially someone of the opposite sex, unless you know them well. Personal space is highly valued in Hong Kong. Do not give clocks as gifts. In Chinese culture, giving a clock is associated with death. Avoid wearing white or black at weddings. These colors are traditionally associated with funerals in Chinese culture. Do not open a gift immediately after receiving it. It is customary to wait until you are alone to open a gift. Avoid tipping in restaurants. Service charge is usually included in the bill in Hong Kong. Do not assume everyone speaks English. While many people in Hong Kong do speak English, it's respectful to learn a few basic phrases in Cantonese. Avoid being loud or boisterous in public. Hong Kong people value quiet and calm behavior. Do not interrupt or speak over someone. It's considered rude and disrespectful. Avoid making negative comments about the food. Food is a big part of Hong Kong culture and criticizing it can be seen as offensive," remarked another expat who made the move to Tai Po, Hong Kong.
