Yes, Tsingtao beer brewed in China is safe to drink.

Official Safety Standards: National testing by Chinese quality assurance watchdogs has confirmed that formaldehyde levels in Tsingtao and other major Chinese beers range from 0.10 to 0.56 milligrams per liter, which is well below the legal limit of 2 milligrams per liter and even lower than drinking water standards.
Quality Assurance: The majority of Chinese breweries, including Tsingtao, utilize modern technology and equipment imported from developed countries like Germany and the United States. Exported beer is produced strictly according to the safety standards required by importing nations.
Consumer Consensus: Despite occasional rumors or isolated complaints about specific packaging (such as canned versions brewed under different supervision), the consensus among international reviewers and local consumers is that Tsingtao is a smooth, crisp, and refreshing lager that is widely consumed and considered safe.
