Is Penang fun when traveling in Malaysia? What are the precautions?

I'd better post it directly to you and help others to the end. Day 1: Depart from Guangzhou-Penang and meet at Baiyun Airport. Full-time employees will check in. Arrange to check into the hotel upon arrival. The next day: diving, underwater tour to Penang-[Baya Island-Coral Island Tour]-Langkawi Hotel (including brunch and dinner) After breakfast, take a bus to the pier and take a speedboat to the coral floating platform. Paya Island, known as the Great Barrier Reef in Nanyang, is one of the marine parks protected by Malaysia Maritime Safety Administration. There are many beautiful natural corals in the waters near the island. There is a wide deck above the coral, and diving equipment and coaches are around the floating platform. You can take one-on-one diving lessons at your own expense. Those who dare not go into the water can go to the glass room under the deck to watch frogmen feed fish, watch the fascinating underwater world, watch natural corals dance with the current, and watch colorful tropical fish swim freely among corals. There are also glass boats to take you to see starfish, sea cucumbers and sea urchins on the shallows. Go to Langkawi after the game and send it to the hotel for rest after dinner. Day 3: Sunny Beach, Cable Car Langkawi-Free Activities [Take part in the natural ecological tour of mangroves at your own expense and visit the magical Golden Palm Peak Island] All spicy (including soft-shelled crabs) (including breakfast and dinner, and take care of yourself after lunch) Free activities after breakfast. Participate in the [Mangrove Natural Ecology Tour Magic Island Tour] at your own expense: Go by speedboat, there are many islands, and you can swim on the beach. Be careful of sea urchins and don't get stabbed; Pregnant woman island-"the lake in the sea" is the special charm of pregnant woman island. You can experience a sea fishing here and have a BBQ barbecue at noon. After eating, take the Langkawi cable car to Majinzhang Peak, and visit the "Oriental Village", "Temurun Waterfall" Waterfall and Langkawi Islands along the way. Those with good eyesight can even go to Tarutao Island in Thailand. Then return to Langkawi to visit Eagle Square. Langkawi is the only duty-free island in Malaysia. Shopping here is super cost-effective! Enjoy a special all-spicy meal of soft-shelled crab for dinner. Then send it back to the hotel to rest. Day 4: Let go of your belly and eat! Durian Mountain on the back of Langkawi-Penang-Luo Fu Mountain-Ji Gu Street-Guanzaijiao (including brunch and dinner), after breakfast, go to Durian Mountain on the back of Luo Fu Mountain, where durian is the best in the world, and everyone can get one to taste. In addition, there are other local fruits such as rambutan and mangosteen. Then, the overseas Chinese culture-Chen Nianya, and the in-laws of China and China-Chen Nianya, these are the evidences for people to explore Nanyang, and they are said to be descendants of Zheng He who stayed in Nanyang. Penang is one of the most inhabited places in Nyonya, and the cultural museum here is a typical home for overseas Chinese students, with a collection of more than 1000 precious antiques and treasures of early Nyonya. Then you can visit historic streets along the way: Single Hui Church in Jining, Indian Temple in Amman, Kannonji and St George's Church in England. Then go to the local specialty shop and tropical chocolate shop. You can eat chocolate such as durian, mango and strawberry for free. As long as you have enough money in your pocket, I suggest you leave some space. Because I later arranged to go to Xinguanjiao to eat local food. There are all kinds of food stalls here, with Malay characteristics and China cuisine. Day 5: Go home
