It depends on how many days you have in a winter vacation. College students have a long winter vacation. If you can practice seriously for two hours every day, no matter whether you have hard or soft writing, you will be able to practice regular script well in a month. The winter vacation for primary and secondary school students is short, but if they practice seriously, their progress will be obvious. The cost varies from place to place, but it should not exceed 1,000 yuan a month.
