What cultural faux pas should I try to avoid making in Wan Chai?

"In Wan Chai, it is considered rude to point with your index finger, instead, use your whole hand to gesture. Avoid discussing politics, especially issues related to Hong Kong's relationship with China, as it can be a sensitive topic. It's also considered impolite to take photos of people without their permission, especially in crowded places like markets. When dining, never stick your chopsticks upright in a bowl of rice as it is associated with funerals. Also, don't tap on your bowl with chopsticks, it's seen as begging. If you're invited to someone's home, it's customary to bring a gift, but avoid giving clocks or pears as they are associated with death and separation respectively. In public transportation, always give up your seat to the elderly, pregnant women, or people with disabilities. It's also important to avoid loud conversations or phone calls in public places as it can be seen as disruptive. Lastly, remember to respect queues and wait your turn, as cutting in line is considered very disrespectful," said another expat in Wan Chai, Hong Kong.
