The restrictions on personal belongings by the railway are: children (including free children) 10kg, diplomats 35kg and other passengers 20kg. The sum of the overall dimensions of each article shall not exceed 160cm. Rod-shaped articles shall not exceed 200cm and the weight shall not exceed 20kg.

If it exceeds 20kg, I suggest you check it. Under normal circumstances, if overweight is found, only the freight for the overweight part will be charged. However, if it is inseparable items, such as washing machines and televisions (assuming 30kg each), the freight will be charged according to the total weight of the items. If the items you want to bring are more expensive, not a whole piece, you can open them and take them away if you don't trust to check them. If you find that the overweight part is too big, it won't be very expensive. If the overweight part is less than 5KG, the freight will not be compensated when leaving the station.
