Today, Nanyang University, or Nantah as it's known in Cantonese, is the site of Singapore's Nanyang Technological University.

Nantah was merged with the University of Singapore to form the National University of Singapore in 1980.

English is now the official language of all universities in Singapore.

The Chinese Heritage Center is housed in the former administration building of Nanyang University.

The center, with a permanent display showcasing the history of Chinese immigrants to Singapore, is the only university research center outside China that specializes in the study of overseas Chinese.

That status is enhanced by a collection of 30,000 books donated by Professor Wang Gungwu, a renowned historian who is now the chairman of the East Asian Institute at the National University of Singapore.

The books, many on Chinese immigration, formed the core of the Wang Gungwu Library, located on the ground floor of the Heritage Center.

According to librarian Luo Biming, many books from the collection are very precious as they can no longer be found on the Chinese Mainland.

"Many were first published during China's Republican Era (1912-1949) but the copies were destroyed during the cultural revolution," he says, referring to the ideology-centered political movement that threw China into tumult between 1966 and 1976.

"In many cases, what we have is the only remaining copy."

Meanwhile, reflecting on the metamorphosis Chinese immigrants in Singapore underwent, both mentally and culturally, Soon points to a group of three pictures, of the same family taken over a period of 20 years.

In the first picture, everyone, from the matriarch who sits in the middle of the front row, to the younger members of the family, and even the toddlers, are dressed in traditional Chinese attire. The adults have long bead necklaces, then considered a part of court regalia.

Then changes gradually take place: the boys from the first picture appear in the second one as teenagers, and are dressed in Western-style suits that are too big for them.

If the second picture shows any sense of unease, the third picture portrays confidence, projected by the young men and women who have grown up.
