What is the most reasonable way to go to Tibet by train from Shandong?

Brothers in Shandong can choose their own trains first. From Beijing to Lhasa, you can take the t28 train, from Qinghai to Tibet via the Tanggula Mountain in Hoh Xil, Qinghai Lake and the beautiful scenery of the Qinghai-Tibet Plateau, and you can visit the grasslands in northern Tibet. Then you just said that you should like the natural beauty of Linzhi, Tibet, because there are snow-capped mountains, grasslands, dense forests and flowing rivers in southern Tibet. You also said that if you like the humanities of the Luzangbujiang River, you can go to Shannan region of Tibet, where there are the first temple and the first palace in Tibet, and you can see the Lamla measures in previous lives, and you can see the simple customs. So what you said about the cost may not necessarily mean that Lhasa is now the tourist season, which will be higher than the off-season, but as far as the scenic spots I just mentioned are concerned, it is estimated that 5,000 yuan will be enough for you, including the fare.
