I want to know the answer to the following question:
What did Lok-Ham Chan claim  Changchub Gyaltsen wanted to remove?
All the background I'm provided with is that "Van Praag asserts that Changchub Gyaltsen's ambitions were to "restore to Tibet the glories of its Imperial Age" by reinstating secular administration, promoting "national culture and traditions," and installing a law code that survived into the 20th century.". Is that enough to answer the question?
Answer: no
