1. No choice. Once in Malaysia, you can only exchange RMB for Malaysian ringgit at the airport. The exchange rate there is more expensive, so you can use 50 yuan for the time being. There are three ways to get to Johor Bahru Airport. A) The cheapest one is AirAsia. It only costs 9.99 pounds (about 22 yuan RMB) to buy tickets online in www.airasia.com by credit card in advance. In addition, airport tax is required. 40 yuan, the flight time is 40 minutes. B) Take the airport bus (green) to Central Station (RM 10, 60 minutes), and then take the train there to Johor Bahru Railway Station (20 yuan, with more than 70 sleepers, 9 hours). C) Take the airport bus (yellow, Xinkai, Www.starwira.com) to Pudulaya, Du Fu Station (10 yuan, 60 minutes), and take a long-distance bus there to Johor Bahru (luxury vip seat in 24 yuan, 4.5 hours, every half hour, at the latest 12.30 pm). A, B, C and C are the best and most economical. 3. It takes four and a half hours from Kuala Lumpur to Johan Bahru (JB for short), and the last bus is 12: 30 in the evening. If you take a taxi directly, it will be about RM 500. Personally, I think it is unnecessary. 4. The address is not far from the Johor Bahru bus stop Lakin.
