"To write proper calligraphy, it is equally crucial to acquire the good qualities from others, and combine them with ours," said the artist. Ung Si Meng made a calligraphy work on the article "Preface to the Forbidden City", which formally published on the People’s Daily in 2010 and has been highly praised. The writing highlights the value of Forbidden City as a world heritage, gives thanks to its architectural magnificence and the fascinating history. It activates the delicate architectural craftsmanship, as well as the ultimate luxury life of the royal family back in time.
