Whether it is convenient to transfer within the station needs to be judged according to the specific train station and line conditions. You mentioned that you place separate orders, one for trains and one for trains. If it is a transfer within the same train station, it is usually an intra-station transfer. However, whether it is convenient or not depends on factors such as the transfer time between the two trains, the distance between the platforms, and the clarity of the transfer instructions. It is recommended that you check the transfer information at the train station in advance, or use the official travel tools to inquire about the specific transfer plan to ensure a smooth transfer.
