The development road of China will be bumpy and even thorny in the next few years, Premier Wen Jiabao told a press conference Sunday rightly after the conclusion of the national legislature's annual session.

He called for unslackened efforts to tackle difficulties, saying "we must have firm confidence."

"No matter how high a mountain is, one can always ascend to the top. The only way out and hope when facing difficulties lies in our own efforts," Wen said.

He also said he holds deep love for the country and vowed strong commitments in the next three years of his term.
